Synthetic paper with multi-layer structure and excellent printing property

摘要

A synthetic paper with a multi-layer structure comprising a biaxially stretched film of an olefinic polymer having a melting point (the peak temperature of the DSC curve) of from 130 DEG C. to 210 DEG C. containing from 5 to 40% by weight inorganic fine powders having a mean particle size of from 0.01 to 10 mu m as a base material layer (A) having adhered to at least one surface thereof a uniaxially stretched layer (B) having a surface roughness of from 0.3 to 1.5 mu m, with the uniaxially stretched layer (B) comprising a propylene alpha -olefin copolymer or a high-density polyethylene having a melting point (the peak temperature of the DSC curve) of from 120 DEG C. to 160 DEG C. which is at least 5 DEG C. lower than the melting point of the olefinic polymer of the base material layer (A) and from 8 to 65% by weight inorganic fine powders having a mean particle size of from 0.01 to 5 mu m, wherein the surfaces of the inorganic fine powders contained in the uniaxially stretched layer (B) are coated with the propylene alpha -olefin copolymer or the high-density polyethylene.
