A thermoplastic resin film (i) which has a degree of dimensional change through heating and cooling (&#x3b1;) in the range of from &#x2212;2% to 2% as measured by thermomechanical analysis in the range of from room temperature to 135&#xb0; C., or which has a degree of thermal shrinkage of 1.8% or lower upon heating at 130&#xb0; C. for 30 minutes or longer; and a label paper employing the same. The label paper has suitability for heated-roll fixing type electrophotographic printers and is satisfactory in curling after printing.

Thermoplastic resin film and label paper employing the same

A porous resin film which comprises 30 to 90 wt % of a thermoplastic resin containing a hydrophilic thermoplastic resin component; and 70 to 10 wt % of an inorganic or organic fine powder was disclosed. The porous resin film of the present invention is valuable as an ink-jet recording medium since the film shows excellent ink absorbing and drying properties even when a large amount of ink is discharged thereon, and thus can produce thereon a high-definition image.

Porous resin film

The invention provides a porous resin film having a good absorption of water content as a solvent for aqueous ink or aqueous paste and a recording medium comprising the porous resin film. The recording medium is characterized by the capability of absorbing an ink without density unevenness even during ink jet recording if the ejected amount of ink is great. The invention lies in a porous resin film comprising: a thermoplastic resin in an amount of 30 to 90% by weight; and an inorganic and/or organic finely divided powder in an amount of 10 to 70% by weight, wherein the inorganic and/or organic finely divided powder is surface-treated with a surface treating agent (A) made of a copolymer of diallylamine salt or alkyl diallylamine salt (a1) with a nonionic hydrophilic vinyl monomer (a2) and an anionic surface treating agent (B), and the porous resin film has a liquid absorption capacity of not smaller than 0.5 ml/m as measured by &ldquo;Japan TAPPI No. 51-87&rdquo;.

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 printing resin film excellent in ink dryability and transferability, and comprising a resin composition comprising (A) from 25 to 65% by weight of a calcium carbonate powder having an oil absorption of from 70 to 200 ml/100 g as determined by JIS-K5101-1991 and (B) from 35 to 75% by weight of a thermoplastic resin.
