US Patent:

43991920, Aug 16, 1983

Filed:

Oct 23, 1981

Appl. No.:

6/314128

Inventors:

Raymond J. Russell - Lincoln Park NJ

Assignee:

Panelographic Corporation - West Caldwell NJ

International Classification:

B32B 2736
B32B 2710
B32B 2308
B32B 2706

US Classification:

428412

Abstract:

Actinic radiation curable coating compositions are provided applicable to many substrates comprising a pentaerythritol-based polyacrylate or polymethacrylate such as pentaerythritol tetraacrylate, a cellulose ester such as cellulose acetate butyrate and a photoinitiator. The compounds are preferably applied to the substrate by spraying a solution of the composition in one or more solvents selected from the group consisting of lower alcohols and ester, ketones having from 3 to 7 carbon atoms and lower alkyl Cellosolves, and removing the solvents. Upon curing in air the compositions form extremely abrasion resistant coatings on the substrate and are also characterized by being scratch resistant and resistant to attack by chemical and organic solvents.

US Classification:

427 531

Abstract:

Actinic radiation curable coating compositions applicable to many substrates and comprising a pentaerythritol-based polyacrylate or polymethacrylate such as pentaerythritol tetraacrylate, a vinyl chloride-vinyl acetate containing polymer, preferably a partially hydrolyzed vinyl chloride-vinyl acetate copolymer, and a photoinitiator are provided. The compounds are preferably applied to the substrate by spraying a solution of the composition in one or more solvents selected from the group consisting of lower alcohols and ester, ketones having from 3 to 7 carbon atoms and lower alkyl Cellosolves, and removing the solvents. Upon curing in air the compositions form extremely abrasion resistant coatings on the substrate.

Filed:

Appl. No.:

6/213479

Inventors:

Raymond J. Russell - Lincoln Park NJ

Assignee:

Panelgraphic Corporation - West Caldwell NJ

International Classification:

C08F 248

US Classification:

264 22

Abstract:

The present invention provides a method of forming a coating on molded polymeric articles formed by curing a polymerizable monomer-containing molding composition in a mold comprised of a material having less bonding affinity for the abrasion-resistant coating than for the cured molding composition. The method comprises: (a) applying to a mold a coating composition comprising a pentaerythritol based polyacrylate or polmethacrylate and, a cellulose ester or a vinyl chloride-vinyl acetate containing copolymer; (b) exposing said coating composition to actinic radiation to form a cured coating; (c) adding to the mold a heat polymerizable monomer-containing molding composition; and (d) polymerizing said molding composition in the form of a molded article, said cured coating bonding to the surface of said molded article.

International Classification:

B32B 2738
B05D 302
C08F 250

US Classification:

428412

Abstract:

Actinic radiation curable coating compositions are provided requiring no photoinitiator or photocatalyst which are applicable to many substrates comprising a dipentaerythritol-based polyacrylate such as dipentaerythritol pentaacrylate, a cellulose ester such as cellulose acetate butyrate or a vinyl chloride-vinyl acetate containing copolymer. The compounds are preferably applied to the substrate by spraying a solution of the composition in one or more solvents selected from the group consisting of lower alcohols and esters, ketones having from 3 to 7 carbon atoms and lower alkyl Cellosolves, and removing the solvents. Roller gravure coatings may also be employed. Upon curing in air the compositions form extremely high abrasion resistant coatings on the substrate and are also characterized by being scratch resistant and resistant to attack by chemical and organic solvents and are stress crack resistant.
