Title:
POWDER/GRANULAR PHOTOCURABLE RESIN COMPOSITION AND ITS PRODUCTION METHOD
Document Type and Number:
Japanese Patent JP2005089520
Kind Code:
A
Abstract:

To provide a powder/granular photocurable resin composition capable of forming a coating film excellent in surface smoothness and outer appearance, also having a high storage stability or blocking resistance.

The powder/granular photocurable resin composition is composed of 100 pts.wt. photopolymerizable resin powder/granule containing a photocurable resin having a low glass transition temperature (a polyester resin and the like) and a photopolymerization initiator, 0.01-1 pts.wt. fine particle antiblocking agent (Si-containing inorganic fine particles such as silica) constituted of primary particles having 5-100 nm average particle diameter, and an optional colorant. The photocurable resin may be a resin composition wherein the ratio of an amorphous resin to a crystalline resin is 50/50-99/1. The amount of the photopolymerization initiator to be used is 0.1-10 pts.wt. based on 100 pts.wt. photocurable resin. The photopolymerizable resin powder/granule has 5-50 μm volume average particle diameter and ≤20 μm standard deviation of the particle distribution. The cured coating film having a high surface smoothness is formed by applying the powder/granular composition onto a porous substrate, followed by heating and photoirradiating it.
