Optical films and methods for manufacturing optical films

Abstract

The particles of this invention contain (meth)acrylic resin and (meth)acrylic acid crosslinked particles, wherein the (meth)acrylic resin contains ring structural units having a ring structure in the main chain. The characteristic feature is that the average elastic modulus E1 of the portion lacking (meth)acrylic acid crosslinked particles and the average elastic modulus E2 of the portion containing (meth)acrylic acid crosslinked particles satisfy the following formula (1). Formula (1) 0.90≦E2 / E1 none
