Title:
TRIPHENYLMETHANE-BASED COLORED COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2015/182680
Kind Code:
A1
Abstract:
A practical range of heat resistance could not be achieved in conventional colored resin compositions that used a triarylmethane derivative. The present invention thus addresses the problem of providing a colored composition having higher heat resistance than conventional colored compositions. The present invention relates to a compound represented by general formula (1), and a polymer or the like having a monomer unit derived from said compound. (In the formula, R1 to R4 are each independently an alkyl group or the like, R5 to R7 are each independently a hydrogen atom or a methyl group, an n number of R8 are each independently a halogen atom, an alkyl group, an aryl group, a hydroxyl group, a nitro group, a sulfo group, an alkoxy group or the like, and n is an integer from 0 to 4. A1 is an alkylene group or the like, and A2 is -NH- or -O-. An- is an aryl group having a substituent with an electron-withdrawing property, a sulfonyl group having a substituent with an electron-withdrawing property, or an anion including an alkyl halide group.)
