A film cassette is disclosed wherein a filmstrip beginning with a relatively short non-protruding leader portion can be advanced automatically to the exterior of the cassette responsive to rotation of a film spool in a film unwinding direction. The filmstrip has one metering perforation per film frame in a relatively long imaging portion and several much closer spaced take-up perforations in its leader portion. Preferably, the take-up perforations are located along a different longitudinal edge ...

An object of the present invention is provide a polyester film useful as base for release film according to which when a ceramic slurry is applied on the release film, formation of pinholes in the ceramic slurry layer is suppressed prominently, and also when a ceramic layer is provided on the release film, thickness variation of the ceramic layer is lessened, thus realizing excellent releasability of the release film.A polyester film for release film, which has a maximum height of projection (Rm...

A polymer composition, for use in making film to wrap warm rubber bales, includes an ethylene copolymer and a minor proportion by weight of a low molecular weight ethylene-based polymer. The comonomer is preferably vinyl acetate. Lower VICAT softening points can be achieved together with good non-stick characteristics at higher temperatures.

Photographic film is dried in a film dryer having a pattern of film guide rollers inside a hollow drying chamber contained in an outer drying housing. A continuous film strip is passed through the chamber and around the rollers so that long lengths of the film between adjacent sets of guide rollers pass through the chamber in substantially parallel directions for exposure to warm drying air passing through the chamber. A supply of warm air is introduced into a supply plenum contained in the hous...

A slide mount has a first portion and a second portion. The first portion includes an interior region, an edge, and a slot extending from the interior region to the edge. A cavity is formed between the first portion and the second portion, and extends to the first edge. A film segment is disposed in the cavity. The slide mount disengageably locks in the film segment. The film segment can be released from the slide mount using an extractor arm. The slide mount can have a locking aperture for rece...

A film containing at least 5 wt % of an aromatic vinyl compound-.alpha.-olefin random copolymer having an aromatic vinyl compound content of from 1 to less than 99.9% by molar fraction and having head-to-tail chain structures comprising at least two aromatic vinyl compound units.

The present invention relates to a film condenser and a metalized film for manufacturing the same. The metalized film comprises a base film formed from an insulating material, and a metal coating layer formed on the base film. A plurality of uncoated portions are formed as area partition margins in the metal coating layer so as to respectively form, in the metal coating layer, a plurality of electrode regions, a plurality of fuse connecting regions surrounded by two or more of the electrode regi...

A hardcoat film is provided which can improve surface hardness and, at the same time, can prevent the hardcoat film per se from being damaged by stress concentration and is less likely to be scratched. The hardcoat film comprises: a transparent substrate; and a multi-layer hardcoat provided on at least one side of the transparent substrate, the multi-layer hardcoat layer comprising two or more hardcoats, the modulus of elasticity .sigma.m of a hardcoat provided closest to the transparent substra...

A composition for film formation and a film obtained by heating the composition. The composition comprises: (A) a hydrolyzate and/or partial condensate of a compound represented by the following formula (1) wherein R.sup.1 and R.sup.2 may be the same or different and each represent an alkyl group having 1 to 5 carbon atoms or an aryl group having 6 to 20 carbon atoms, and n is an integer of 1 or 2; (B) a metal chelate compound represented by the following formula (2) wherein R.sup.3 represents a...
