The present invention provides a hard coat film having excellent adhesion to a hard coat layer when a cycloolefin polymer film is used as a base material. The hard coat film of the present invention comprises a hard coat layer containing an ionizing radiation curable resin laminated on at least one surface of a cycloolefin polymer base film through a primer layer. This primer layer contains a modified polyolefin resin in which a polyolefin resin is graft-modified with an α,β-unsaturated carboxylic acid or a derivative thereof, and a (meth)acrylic acid ester. In this modified polyolefin resin, the graft weight of the α,β-unsaturated carboxylic acid or derivative thereof is 0.4 to 7 wt. % when the amount of the modified polyolefin resin is taken as 100 wt. %.

Hard coat film and method for producing same

A hard coat film having excellent adhesion (particularly adhesion over time) to a hard coat layer when a cycloolefin polymer film is used as a base material. The hard coat film comprises a hard coat layer containing an ionizing radiation curable resin laminated on at least one surface of a cycloolefin polymer base film via a primer layer. The primer layer has an arithmetic average surface roughness (Ra) in the range of 0.5 nm to 15.0 nm, and a surface of the primer layer has a static friction coefficient in the range of 0.6 to 2.0.

An antiglare hard coat film formed by providing an antiglare hard coat layer containing fine particles and a resin on a transparent film. When an average value of height in an evaluation region on a surface of the antiglare hard coat film is set at zero (0), a maximum cross sectional height represented by a difference between a height maximum value in the evaluation region and a height minimum value in the evaluation region is from 1.0 to 3.0 &#x3bc;m, and an average inclination angle of unevenness on the surface of the antiglare hard coat film is 1 degree or less. The total value of the transmissive clarity measured through four optical combs using a transmissive clarity measuring device according to JIS K 7105-1981 is 280% or more, and the value of the transmissive clarity measured through each optical comb is 70% or more, respectively.

Antiglare hard coat film

An antiglare hard coat film is provided in which light transmittance is high without giving antiglare properties more than necessary, a haze value is low, transparency is excellent, image clarity is high, glare of an image is suppressed, whitishness (white blur) of the film is reduced, contrast deterioration is suppressed, and visibility of the display is improved as compared with prior-art antiglare films. This antiglare hard coat film is formed by providing an antiglare hard coat layer containing organic particulates and a resin on a transparent film. When an average value of height in an evaluation region on the surface of the antiglare hard coat film is set to zero (0), a maximum sectional height represented by a difference between a height maximum value in the evaluation region and a height minimum value in the evaluation region is 0.6 &#x3bc;m or less.

A game ball comprises an inflatable rubber bladder, a layer of windings over the bladder, panels of sponge rubber over the wound bladder, rubber channels between adjacent panels of sponge rubber, and panels of cover material over the panels of sponge rubber. Before the panels of cover material are applied, the bladder, sponge rubber, and channels are cured in a heated mold to bond the rubber channels and the sponge rubber to the wound bladder. After the panels of cover material are applied, the ball is heat molded to bond the cover material to the rubber channels and the sponge rubber.

A thermo-transfer sheet is composed of a base film and an ink layer to be transferred having a softening point of more than 120.degree. C. A label is formed by the thermo-transfer sheet and provided with an image ink layer formed on a thermo-transfer image receiving sheet through a temperature-sensitive adhesive layer and the image ink layer has a softening point of more than 120.degree. C. The thermo-transfer sheet and the thermo-transfer image receiving sheet are prepared and a temperature-sensitive adhesive layer is formed on at least one of the surface of the thermo-transfer sheet or the transfer ink layer of the thermo-transfer image receiving sheet. These sheets are laminated and the laminated sheets are heated by means of a thermal head to thereby transfer the image ink layer having a softening point of more than 120.degree. C. on the thermo-transfer image receiving sheet. According to these processes, a label such as bar code is manufactured with an excellent durability such as friction-proof property, solvent-proof property and heat-proof property.
