42763673, Jun 30, 1981

Filed:

Dec 26, 1979

Appl. No.:

6/107395

Inventors:

Richard E. Merrill - Wakefield MA
Arthur A. Massucco - Natick MA

Assignee:

Arthur D. Little, Inc. - Cambridge MA

International Classification:

G03C 500

US Classification:

430302

Abstract:

A lithographic printing plate in which the oleophilic imaging areas are formed as a thin cross-linked block copolymer film adhered to the hydrophilic surface of a backing plate. The block copolymer comprises blocks of copolyacrylate and polyurethane wherein the copolyacrylate blocks are a copolymer of a hydroxy-containing acrylate and a second acrylate component comprising one or more esters of acrylic acid or methacrylic acid or mixtures thereof and the polyurethane blocks are formed of polyoxybutylene as the prepolymer component. In forming the printing plate the block copolymer is deposited as a thin film containing an ultraviolet initiator and a cross linking promoter and the cross-linked imaging areas are formed by exposure to ultraviolet radiation.

Abstract:

A lithographic printing plate in which the oleophilic imaging areas are formed as a thin cross-linked block copolymer film adhered to the hydrophilic surface of a backing plate. The block copolymer comprises blocks of copolylacrylate and polyurethane wherein the copolyacrylate blocks are a copolymer of a hydroxy-containing acrylate and a second acrylate component comprising one or more esters of acrylic acid or methacrylic acid or mixtures thereof and the polyurethane blocks are formed of polyoxybutylene as the prepolymer component. In forming the printing plate the block copolymer is deposited as a thin film containing an ultraviolet initiator and a cross linking promoter and the cross-linked imaging areas are formed by exposure to ultraviolet radiation.

Abstract:

Pencils made with a resin-based sheath to replace wood sheaths. A sheath material consisting essentially of a resin binder, a fibrous filler and a metallic soap is extruded around a marking core. The resulting extrudate is immediately chilled after leaving the die, and cut into pencil lengths. The apparatus includes core feeding and transport means, core preheating means and chilling means. The resulting pencils possess the physical qualities associated with wood-sheathed pencils due to the fine, closed cell structure of the sheath material. The surface of the sheath is smooth and may be coated with a pigmented resin or painted.

US Classification:

Abstract:

A method for treating a surface of a substrate to render it nonfogging and the resulting article formed by the treatment. A thin film coating of a block copolymer containing alternating blocks of polyurethane and a hydrophilic copolyacrylic is adhered to the surface to be made nonfogging. The copolyacrylic is a copolymer of a hydroxy substituted acrylate and an ethylenically unsaturated acid such as acrylic acid. By varying the weight ratio of polyetherurethane/copolyacrylic it is possible to vary the flexibility of the coating and hence to widen the range of substrates to which the treatment is applicable, e. g. , from flexible wrapping material to rigid mirrors.

US Classification:

Abstract:

A dry system for forming and transferring images is provided. The system comprises a photoactive component comprising a tacky photohardenable layer on a selected carrier sheet and a transfer component comprising a frangible color layer on a selected carrier sheet. The two components are disposed with their photohardenable and color layers in air-free contact with one another and then subjected to irradiation with actinic radiation in accordance with a selected image pattern so as to cause selected portions of the photohardenable layer to harden and fuse to confronting portions of the color layer. Then the two components are separated whereby the fused portions of the color layer are separated from its carrier sheet and transferred to the photoactive component. Thereafter the color layer remaining on the transferable component is coated with a pressure-sensitive adhesive. Finally, the transferable component is positioned with its adhesive coating engaging a receptor substrate and the rear side of its carrier sheet is rubbed hard or burnished with a suitable implement so as to cause the remaining image-defining portions of the color layer to separate from its carrier sheet and adhere to the receptor substrate.

International Classification:

B05D 306

US Classification:

427 54

Abstract:

A method for improving adhesion of nonfogging film coatings comprising a block copolymer containing alternating blocks of polyurethane and a hydrophilic polyacrylic, to a polymeric substrate by subjecting the substrate to a controlled exposure to UV irradiation. Exposure may be prior to or following casting the nonfogging coating in place on the substrate. By varying the weight ratio of polyurethane/polyacrylic it is possible to vary the flexibility of the coating and hence to widen the range of substrates to which the coating may be applied, e. g. , from flexible wrapping material to rigid mirrors.

Abstract:

Screen printing stencils are prepared by affixing to a printing screen substrate an indicia-defining, ultraviolet-sensitive film and cross-linking the film by exposure to ultraviolet radiation. The coating compositions used to form the film comprise copolyacrylate/polyurethane block copolymers, in which the copolyacrylate blocks are copolymers of at least one hydroxy-containing acrylate and at least one acrylate or methacrylate which may be partially substituted with bromine, ultraviolet initiators and cross-linking monomers. Screen printing stencils are provided which are compatible with both water-based and oil-based inks. The disclosed screen printing stencils are used in improved screen-printing methods.
