Abstract: The present invention provides a hard coat film that is provided with a hard coat layer via an easy-bonding layer on at least one surface of a cycloolefin film, has excellent temporal adhesiveness under normal condition and under moisture and heat resistant condition, and has no crack occurrence under the heat resistant condition. A hard coat film 10 of the present invention is provided with a hard coat layer 3 via an easy-bonding layer 2 on at least one surface of a cycloolefin film 1. The easy-bonding layer 2 includes a mixture of a polyolefin based resin and a styrene-acryl based resin, and a blending ratio thereof is in the range of, for example, from 95/5 to 40/60. Further, the hard coat layer 3 includes an ionizing radiation curable resin having a weight-average molecular weight of 700 or larger and 3600 or smaller.

Abstract: An electrophotographic OHP sheet comprising a transparent support and a toner-receiving layer formed on one side of the support, with the toner-receiving layer having suitability for toner fixation at a temperature in the neighborhood of 160° C. to 200° C. and comprising (a) a resin having a softening point of from 180° C. to about 190° C., (b) a resin having a softening point of from 110° C. to 140° C. and (c) a plasticizer having a plasticizing efficiency of 1.1 or below.

Abstract: A heat-sensitive adhesive sheet for bonding a pair of information-recorded faces, belonging to the same sheet or two different sheets of recording material, together by application of heat thereto, which comprises three or more layers, including a support and a synthetic resin layer coated on either side of the support, having a peeling resistance ranging from 10 to 150 g/50 mm between the support and each synthetic resin layer in the T-peel test performed at a peeling speed of 300 mm/min. in the atmosphere of 20.degree. C.
