Abstract:
A photosensitive resin composition which comprises:(1) a core phase consisting essentially of a non-crosslinkable hydrophobic polymer (A) having a glass transition temperature at 5.degree. C. or lower;(2) a shell phase consisting essentially of a hydrophilic polymer, which covers said core phase to form dispersed particles;(3) a matrix phase consisting essentially of a mixture of a hydrophobic polymer (B) which is immiscible with the hydrophobic polymer (A) and a non gaseous ethylenic unsaturated compound; and(4) a photopolymerization initiator, and the difference between refractive index of said hydrophobic polymer (A) of said core phase (1) and that of said mixture of said hydrophobic polymer (B) and said ethylenic unsaturated compound of said matrix phase (3) being 0.010 or less.
