Abstract
Abstract The present invention relates to a deposited plastic film comprising:a deposited plastic film comprising:a plastic film;a coating layer which is formed on at least one surface of said plastic film and comprises a cured resin composition obtained by curing a resin composition comprising 6 to 80% by weight of an oxazoline group-containing water-soluble polymer; anda deposit layer which comprises a metal, metal oxide or mixture thereof and is formed on a surface of said coating layer.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
166 words
A process for producing a deposited plastic film which comprises: a plastic film; a coating layer which is formed on at least one surface of said plastic film and comprises a cured resin composition obtained by curing a resin composition consisting essentially of 10 to 80% by weight of an oxazoline group-containing water-soluble polymer and at least one resin selected from the group consisting of a water-soluble or water dispersible acrylic resin, a water-soluble or water-dispersible polyurethane resin and a water-soluble or water-dispersible polyester resin; and a deposit layer which comprises a metal, metal oxide or mixture thereof and being formed on a surface of said coating layer; which process comprises: obtaining an amorphous sheet; stretching said amorphous sheet in longitudinal direction; applying the resin composition for forming said coating layer on said longitudinally stretched film; stretching said coating layer in transverse direction to obtain a biaxially stretched film; heat-treating said biaxially stretched film; and applying the deposit layer on the surface of the coating layer.
Claim 2
Dependent Claim
