Study on Behaviors and Their Application of Solid State Organic Dyes

Abstract

The authors have found that physical and chemical properties of solid state organic dyes were changed by light irradiation or thermal treatment. The photochemical change was more sensitive for ultra-violet light comparing with visible light. The changes by irradiation occured for the properties of solubility, melting point, light absorption and adhesion to the substrate.
By using these changes, fair dye patterns were formed by some simple fixing after imagewise illumination. From the hologram recording by Argon laser, the resolution of image was about 1000lines/mm.
