A composition for forming a photosensitive coating is disclosed which includes:

O-naphthoquinone diazide photosensitive coating composition containing a

A matted film is disclosed which includes a synthetic resin film, and a mat layer provided over at least one surface of the film and containing a matting agent which is a mixture of 50-95% by weight of an organic filler having an average particle size of 10 .mu.m or less and 5-50% by weight of an inorganic filler having an average particle size of 10 .mu.m and selected from sericite, calcined sericite, kaolin minerals, calcined kaolin minerals, pyrophyllite, calcined pyrophyllite and mixtures thereof.

Matted film containing a matting agent consisting of an organic filler

A composite film is disclosed which includes (a) a synthetic resin substrate film having a roughened surface, and (b) a thin, slippery, electrically conducting layer coated over the roughened surface. The conducting layer contains 2-10% by weight of carbon black, 10-40% by weight of a fluorine resin, 25-78% by weight of a hardened binder resin selected from hardened amino resins, hardened phenol resins and mixtures thereof, and 7-25% by weight of a modifying resin selected from polyurethane resins, acrylic resins, polyester resins and mixtures thereof, the total amount of the hardened binder resin and the modifying resin being 50-85% by weight.

Composite film having slippery, electrically conducting surface

A composite paper suitable for use as writing paper, printing paper or copying paper is disclosed which includes a synthetic resin film having a thickness of 12-30 .mu.m, and a paper sheet laminated on each side of the synthetic resin film and having a Bekk smoothness of 60-120 seconds, a density of 0.8-1.0 g/cm.sup.3, a degree of sizing of 0.5-1.5 seconds and a thickness of 20-25 .mu.m.
