Title: WHITE POLY(LACTIC ACID)-BASED RESIN LAYER, LAYERED PRODUCT, CARD BASE, CARD, AND PROCESS FOR PRODUCING WHITE POLY(LACTIC ACID)-BASED RESIN LAYER
Abstract:
Provided are: a white poly(lactic acid)-based resin layer which is suitable for use as card bases; a layered product; a card base; a card; and a process for producing the white poly(lactic acid)-based resin layer. The white poly(lactic acid)-based resin layer comprises a poly(lactic acid)-based resin (A) and an incompatible resin (B) which has a storage modulus (E') at 80ºC of 700-5,000 MPa and is incompatible with the poly(lactic acid)-based resin (A), the content of the incompatible resin (B) being 4.5-50 mass% with respect to the total mass of the poly(lactic acid)-based resin (A) and the incompatible resin (B), the white poly(lactic acid)-based resin layer having been stretched in an areal stretch ratio of 16 or less.
