RESIN COMPOSITION FOR LASER ENGRAVING, FLEXO PRINTING PLATE PRECURSOR FOR LASER ENGRAVING AND PROCESS FOR PRODUCING SAME, AND FLEXO PRINTING PLATE AND PROCESS FOR MAKING SAME

摘要

Disclosed are a resin composition, a flexo printing plate precursor, a process for producing a flexo printing plate precursor, a process for making a flexo printing plate, and a flexo printing plate having a relief layer produced by the process for making a flexo printing plate. The resin composition comprises 1 to 25 wt % of colorless resin particles having a volume-average particle diameter of 0.2 to 30 μm, 1 to 15 wt % of a photothermal conversion agent capable of absorbing light having a wavelength of 700 to 1,300 nm, and 2 to 95 wt % of a binder polymer, in which the 20% weight-reduction temperature of the colorless resin particles in thermogravimetric analysis under an inert gas atmosphere is from 200 to 600° C.
