    摘要: Provided is a photosensitive composition employing, as a photopolymerization initiator, a compound useful as a highly-sensitive photopolymerization initiator that has excellent stability and low sublimability, and that efficiently absorbs and is activated by near-ultraviolet rays at, for example, 365 nm. A photosensitive composition includes a photopolymerization initiator including General Formula (I) below (A), and a polymerizable compound having an ethylenically unsaturated bond (B). Preferred, among compounds represented by General Formula (I), are compounds in which R 10 is a hydrogen atom, or a C 1-12 alkyl group that is not substituted or that is substituted by a hydroxyl group, a carboxyl group, a halogen atom, a cyano group, or a nitro group.

    摘要: A process for producing a pyrophosphate, particularly melamine pyrophosphate useful as a flame retardant, efficiently in high yield is provided. The process comprises firing an orthophosphate, preferably melamine orthophosphate, in the presence of a silicone oil, preferably methylphenyl silicone oil preferably at 120° to 350°C. Examples of useful firing equipment include a hot air dryer, a kneader, a Henschel mixture, a fluidized bed dryer, a rotary kiln, a paddle dryer, an extruder, a vibrating dryer, a far-infrared conveyor furnace, and a microwave firing furnace.
