摘要:
An electrophotography photosensitive plate having an interfacelayer between a substrate and a photosensitive layer. Said interfacelayer comprises the mono- or co-polymer of the unit components represented by the general formula: ##STR1## In said formula R is a hydrogen atom or a methyl group; A is ##STR2## wherein R.sub.1, R.sub.2 and R.sub.3 each are lower alkyl, phenyl or benzyl groups, and further R.sub.2 and R.sub.3 may be taken together to form a ring, or ##STR3## wherein B is a nonmetallic atom selected from the group consisting of carbon, nitrogen and sulfur atoms, necessary to form a 5-6 membered heterocycle nucleus with the --N.sup.+ .dbd.C--; X.sup.- is an anion; and Y is a substituted or unsubstituted alkylene group.
摘要:
A photographic film which comprises (A) a support, having two sides, (B) at least one light-sensitive emulsion layer on one side of said support (A), and, (C) at least one layer containing a compound represented by formula [I]and a hydrophobic polymer (first layer) and at least one layer containing an antistatic agent (second layer), said first and second layers being placed on the other side of said support (A) and said first layer being placed closer to said support (A) than said second layer: ##STR1## wherein, R.sub.1 represents a carboxylic acid residue having from 12 to 24 carbon atoms and R.sub.2, R.sub.3 and R.sub.4 represent independently hydrogen atoms or organic acid residues having from 1 to 24 carbon atoms.
摘要:
A film employed in a liquid crystal display member is disclosed. The film has film thickness of 20 to 60 μm and variation in the film thickness within ±3.0 percent of the standard film thickness.
摘要:
Disclosed is a method of producing a support for a photographic paper, which comprises applying primary irradiation of electron beams to at least one coated layer formed on one side or both sides of a substrate and curable by irradiation of electron beams, bringing the surface of said coated layer into contact with a form member and then peeling it from the form member, followed by applying secondary irradiation of electron beams to the coated layer. The primary irradiation is carried out in the manner that the surface of the coated layer may hold shapes substantially corresponding to shapes on the surface of the form member at the stage where the coated layer has been peeled off from the form member.
摘要:
A multi-layer light-sensitive photographic material comprising a support and a light-sensitive layer, which have a surface layer which does not adhere even under a high temperature and high humidity conditions when the front surface layer thereof is contacted with the other surface layer and which is hardly subject to scratching and free from the so-called "blooming" phenomenon.The light-sensitive material according to this invention comprises, in at least one of the front and back sides thereof, at least one light-insensitive layer containing a high polymer having at least 20% by weight of a repeating unit represented by the formula (I): ##STR1## wherein R.sup.1 represents a hydrogen atom or a methyl group, and R.sup.2 represents a straight chain alkyl group having 12 to 24 carbon atoms.
