Title:
MULTILAYER FILM AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2013/145875
Kind Code:
A1
Abstract:
Provided is a multilayer film, in which a resin layer obtained using a resin (α) is provided on at least one surface of a polyester film, and which satisfies the conditions (I)-(IV) described below.
(I) The resin layer has a thickness of 80-500 nm.
(II) The resin layer has a pencil hardness of F or higher.
(III) The multilayer film has a haze of 3.0% or less.
(IV) The resin (α) is a resin that is obtained by heating a resin composition, which contains a resin (A) that has a hydroxyl group and an acryloyl group and a melamine compound (B) that has a methylol group, at 150°C or higher.
This multilayer film has a transparent resin layer that has a predominantly thin thickness of 500 nm or less, while having high hardness and excellent oligomer precipitation inhibiting properties.
