COLOR-CHANGING MATERIAL COMPOSITION AND COLOR-CHANGING MEMBRANES MADE BY USING THE SAME

摘要

A color-changing material composition which comprises a binder resin comprising a copolymer of a methacrylic ester and methacrylic acid having a specific structure (Component A), at least one fluorescent coloring matter (Component B) and a monomer and/or oligomer having a photopolymerizable ethylenically unsaturated group (Component C) and color-changing membranes formed by curing the color-changing material composition are provided. Degradation of the color-changing membrane due to continuous lighting of a light source can be decreased, the increase in viscosity of the composition can be suppressed, and deterioration of rhodamine can be prevented by using the color-changing material composition and the color-changing membrane using the composition.
