Abstract
A reactive microgel suitable for a photosensitive resin composition for a water-developable flexographic printing plate, which has an average particle diameter to 10 .mu.m, and is formed of PA1 microgel particles, as a core, synthesized from an acrylic monomer in an aqueous medium in the presence of an oil-soluble initiator and in the presence of a reactive polymer emulsifier which is an adduct of a neutralized product of an acrylic copolymer having a tertiary amino group with a compound having an epoxy group and an .alpha., .beta.-unsaturated double bond, and a nonionic emulsifier having an HLB of 12 to 16, and PA1 a compound having an epoxy group and an .alpha., .beta.-unsaturated double bond, attached to surfaces of the microgel particles.
