A polymerizable compound has a practical low melting point, excellent solubility in a general-purpose solvent, and can produce an optical film at low cost, exhibits low reflected luminance, and achieves uniform conversion of polarized light over a wide wavelength band, an optically anisotropic article. A carbonyl compound is useful as a raw material for producing the polymerizable compound. (In the formula (I), Y

Compounds of the formula (I) and (IA) wherein X is -O(CO)-; R1 is C1-C12haloalkyl or C6-C10haloaryl; R2 is located in position 7 of the coumarinyl ring and is OR8; R2a, R2b and R2C independently of each other are hydrogen; R3 is C1-C8haloalkyl or C1-C8haloalkyl; R4 is hydrogen; and R8 is C1-C6alkyI; are suitable as photosensitive acid donors in the preparation of photoresist compositions such as used for example in the preparation of spacers, insulating layers, interlayer dielectric films, insulation layers, planarization layers, protecting layers, overcoat layers, banks for electroluminescence displays and liquid crystal displays (LCD).
Described herein are water-soluble UV-absorbing vinylic monomers and their uses in preparing UV-absorbing contact lenses capable of blocking ultra-violet (“UV”) radiation and optionally (but preferably) violet radiation with wavelengths from 380 nm to 440 nm, thereby protecting eyes to some extent from damages caused by UV radiation and potentially from violet radiation. This invention also provides a UV-absorbing contact lens.
