Method and apparatus for curved-surface transfer

There is provided a transfer sheet for provision of a pattern on a three-dimensional object, comprising: an olefinic thermoplastic elastomer film as a substrate film; and at least a pattern layer as a transfer layer provided on the substrate.

A decorative material including a substrate and an abrasion-resistant coating layer formed thereon. The abrasion-resistant coating layer includes spherical particles (A) having an average particle diameter of 3 to 50 micrometers, and a binder (B) including crosslinkable resins. The amount of the spherical particles (A) is from 5% to 50% by weight of the total amount of the components (A) and (B). The hardness of the spherical particles (A) is higher than of the binder (B), and The average particle diameter d (micrometers) of the spherical particles (A) fulfills the following inequality (1):

Decorative material having abrasion resistance

A lens array sheet according to the present invention, comprising a transparent substrate, a lens array having lens elements that are one-dimensionally or two-dimensionally formed on the front surface of the transparent substrate, and a cluster having a large number of cluster members randomly formed in a prism shape on the rear surface of the transparent substrate, each of the length, the width, and the height of each of the cluster members being in the range from the wave length of source light to 500 .mu.m. Thus, a lens array sheet that effectively uses light energy of the light source, maintains the light condensing effect, prevents the luminance from deteriorating, homogeneously distributes the luminance on the light emitting surface, prevents equal-thickness interference fringes and wasteful light dispersion to out of the angular range of visual angle can be provided. In addition, a surface light source having the lens array sheet is provided. Moreover, a bright transmission type display device having the surface light source is provided.
