Disney Enterprises, Inc. - Burbank 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.

Appl. No.:

7/779410

Inventors:

Kathy M. Flynn - Tustin CA
Vinai M. Tara - Anaheim CA
Kathleen L. Nelson - Pasadena CA

Assignee:

Morton International, Inc. - Chicago IL

International Classification:

G03C 173

US Classification:

430280

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.

International Classification:

G03F 700

US Classification:

430 7

Abstract:

Color transparencies having more than one imaged dichroic filter, and an imaged neutral density filter, layered on one side of a single glass substrate, and processes for making the same, are disclosed. In one embodiment, the color transparency is produced by a deposition process including the steps of coating a glass substrate with a photoresist and developing an image thereupon, depositing alternating layers of high and low refractive index dielectrics to form a dichroic layer of a primary subtractive color, stripping the photoresist from the glass, preparing at least one additional imaged dichroic filter on the first, and preparing a neutral density filter on the substrate on the side having the layered dichroic filters. A red antihalation coating may be applied to the lower surface of the glass substrate prior to exposing the photoresist to prevent undesirable exposure of additional portions of the photoresist layer. In an alternative embodiment, an etching process is utilized whereby stop-etch layers are deposited between each layer of the color transparency.
