Described is a thermoplastic resin film having on a surface thereof a hydroxy-modified imine polymer containing repeating units represented by the following general formula (I) in an amount of 5 mol % or more based on the total of repeating units. This thermoplastic resin film has ink transfer, adhesion and aging stability, and excellent printability of generating no back ghost when offset printing using oxidation polymerization type ink is performed on both faces

Thermoplastic resin film satisfactory in printability

A process for treating a surface of a thermoplastic resin film (i) which includes subjecting the surface of the thermoplastic resin film (i) to a first oxidation treatment, coating the oxidized surface with a surface modifier, subsequently stretching the film, subjecting that surface of the thermoplastic resin film (i) which has been coated with the surface modifier to a second oxidation treatment, and then coating the oxidized surface with a surface modifier.

Processes for treating a surface of a thermoplastic resin film

A thermal transfer image-receiving sheet comprising (1) a support comprising (a) a surface layer comprising a biaxially stretched film of a thermoplastic resin containing from 2 to 60% by weight of titanium dioxide fine powder and (b) a base layer comprising a biaxially stretched microporous film of a thermoplastic resin containing from 10 to 45% by weight of an inorganic fine powder and (2) an image-receiving layer provided on surface layer (a) of support (1), in which support (1) has a void volume of from 30 to 60% and a density of from 0.50 to 0.78 g/cm.sup.3, and surface layer (a) of support (1) has a center-line average roughness of not more than 0.5 .mu.m and a Bekk's smoothness of from 4,000 to 100,000 sec. The thermal transfer image-receiving sheet has an excellent cushioning effect due to the number of microvoids present in the support thereof and high sensitivity in a middle tone region owing to the titanium dioxide present in the surface layer of the support to provide a clear image having a high density even with reduced printing energy.
