Es wird ein kontinuierlich arbeitendes Verfahren zur Herstellung von dickengenauen und dickenkonstanten Photopolymerplatten beschrieben, bei dem die Bestandteile der Photopolymerschicht in einem Schneckenextruder aufgeschmolzen werden, die Schmelze mit einer Zahnradschmelzepumpe der Breitschlitzdüse zugeführt wird, wobei die aus der Breitschlitzdüse austretende Schmelze in einem daran anschließenden Kalanderspalt keinen Rollwulst ausbildet.
Die in der Weise hergestellten Photopolymerplatten weisen eine große Homogenität der Bestandteile der photopolymerisierbaren Mischung auf, zeigen eine hohe Dickengenauigkeit und -konstanz, sind transparent, neigen nicht zur Stippenbildung und gewährleisten eine hohe Lagerstabilität.
A dental composition which comprises (A) a phosphoric acid group-containing monomer, (B) a carboxylic acid groups-containing monomer and (C) water as main components in amounts of 0.5 to 50 % by weight, 1 to 50 % by weight and 5 to 90 % by weight, based on the composition, respectively; and a dental adhesive kit comprising a dental primer composition containing the monomer (A) ad water and an adhesive containing a carboxylic acid-containing polyfunctional monomer and a polymerizable initiator.
This invention relates to use of a copolymer of a high acid value macromonomer which is obtained through copolymerization of specific monomeric components including methacrylic acid in the presence of a metal complex which is a catalytic chain transfer agent or an addition cleavage-type chain transfer agent, and optionally a radical-polymerization initiator, or this macromonomer into which a polymerizable unsaturated group is further introduced, with an ethylenically unsaturated monomer; and said copolymer into which further a long chain alkyl group is introduced; as pigment-dispersing resins to be used in water-based paint.
A dental adhesive containing an acidic group-containing radically polymerizable monomer, a non-acidic radically polymerizable monomer, a chemical polymerization initiator and a filler, as well as a 2,4-diphenyl-4-methyl-1-pentene. When the dental adhesive is used for adhering a crown restorative to the tooth, an excess of cement swelling from the surface of adhesion can be favorably removed, the curing time can be suitably adjusted without decreasing the strength of adhesion to the tooth, and a change in the color tone of the cured body can be effectively suppressed.

Provided is a photosensitive resin composition containing: one or more kinds of alkali-soluble resins selected from a polyimide, a polybenzoxazole, a polyimide precursor, a polybenzoxazole precursor, and a copolymer formed of two or more polymers selected from the preceding substances; and a photosensitizer. The photosensitive resin composition further contains a compound represented by general formula (1). Even when a cured film is fired at low temperature, the photosensitive resin composition exhibits superior adhesion properties with metallic materials, particularly copper, and also exhibits high chemical resistance.
