Filed:

Nov 4, 1998

Appl. No.:

9/185846

Inventors:

Eric C. Haseltine - Manhattan Beach CA

International Classification:

G02B 300

US Classification:

359809

Abstract:

A special effect system and method includes an image panel having a surface coated with phosphor particles and a video screen that projects a transmitted predetermined display. The phosphor coated surface of the image panel is placed in close proximity to the video screen. The phosphor particles that overlap and are thus exposed to the predetermined display are excited by the wavelength emissions of the display and undergo phosphorescence in a wavelength range of human-visible light. Thus, when the panel is removed from the screen, a glow in the dark, "secret" message or image, special effect is revealed.

Abstract:

A photoimageable composition for forming a solder mask has a photopolymerizable acrylate chemical system which renders exposed portions insolvable to alkaline aqueous developers and an epoxy chemical system which hardens the composition after exposure and development. The acrylate chemical system comprises acrylate monomers, epoxy-acrylate oligomers and a photoinitiator. The epoxy chemical system comprises an epoxy resin and a curative therefore. The composition further comprises a cross-linking agent which is reactive with hydroxyl groups of the acrylate and epoxy chemical systems.
