摘要:
Solvent-free hot melt coating compositions composed of a solid linear alcohol, a thermoplastic binder, and a wax which are solid at room temperature, with a melting point of about 75° C. or greater, that when heated to a temperature between about 90° C. and about 135° C., forms a molten coating composition having a viscosity between 100 cps and 1200 cps and method for preparing same.
摘要:
Solid, solvent-free inks are provided for use in hot melt flexographic printing. The ink is composed of a pigment; a thermoplastic binder which is an ethylene copolymer, a hydrocarbon resin, or a combination thereof; a wax which is a highly branched hydrocarbon wax, a polyethylene homopolymer wax, an oxidized polyethylene wax, an animal wax, a vegetable wax or combinations thereof; a solid linear alcohol; and, a dispersing agent. The ink may also contain a solid plasticizer. The solid ink has a melting point of about 75° C. or greater, and when heated to a temperature between about 90° C. and about 135° C., a molten ink is formed which has a viscosity between about 100 cps and about 1200 cps. The solid inks are used in melt flexographic printing by heating the ink to a temperature greater than about 90° C. to form a molten ink which has a viscosity between about 100 cps and about 1200 cps; applying the molten ink to the surface of a heated anilox roller in operational contact with a heated flexographic printing plate; and printing the applied molten ink from the printing plate onto a substrate such as conventional print stock, polymeric films, metal sheets, etc.

摘要:
A coating composition based on a thermoplastic copolymer prepared by polymerizing one or more ethylenically unsaturated monomers in the presence of a fully reacted polyurethane. The resulting copolymer can be coated as a clear film, air dried and has particular utility, when combined with pigments and metallics, in automotive finishes.
摘要:
A hot melt ink composition containing a an alkylene distearate which improves the color strength of the ink and is formed as a reaction product of a C4-C8 diol and at least one acid selected from the group consisting of a C16-C18 monofunctional acid and a C9-C10 difunctional acid.
摘要:
A printing plate is prepared by the process comprising: (a) providing a substrate; and (b) applying by ink jetting to the substrate a fluid composition comprising a cationic polymer and an anionic polymer, in non-aqueous solvent. The ionic polymers interact and adhere to the substrate, so that after drying a durable printing plate is formed, without chemical development. The printing plate of this invention is capable of extended press run length and advantageously avoids the need of chemical development.
摘要:
An energy curable printing ink composition containing a branched polyester comprising monofunctional and difunctional components having an excess functionality of about 0.1 to 0.20. Also described is a method of reducing misting and/or dot gain in an energy curable printing ink composition by adding such branched polyesters to the composition.
摘要:
A fluid composition suitable for ink jetting upon a substrate, which includes a copolymer having a low surface energy and a plurality of tertiary amine sites, where the tertiary amine sites are at least partially neutralized with an acid; a nonionic or cationic surfactant; and water. The fluid composition may be used to prepare a printable media comprised of a substrate and an ink receptive thermoplastic image layer supported on the substrate; where the ink receptive layer contains a copolymer having a low surface energy and a plurality of tertiary amine sites, the amine sites being at least partially neutralized with an acid. The invention also relates to a method for preparing a printable media by applying a fluid composition onto a substrate having at least one basic surface by means of an ink jet printing apparatus; where the fluid composition contains a copolymer having a plurality of tertiary amine sites, the amine sites being at least partially neutralized with an acid, and drying the fluid composition.
摘要:
A printing plate is prepared by the method comprising: (a) providing a substrate; and (b) applying by ink jetting to the substrate a fluid composition comprising a compound which comprises at least one nitrogen-containing heterocyclic moiety, providing a printing plate that is ready-to-use on a press without having to develop it. The printing plate of this invention is capable of extended press run length and advantageously avoids the need of chemical development.
摘要:
A printing plate precursor for direct receipt of an image-wise applied ink receptive layer the precursor having a desorbable surfactant adsorbed on at least one surface in an amount effective to improve the resolution of the subsequently image-wise applied ink receptive layer. The printing plate precursor can be used to prepare a printing plate having improved resolution. The printing plate may be prepared by (a) applying a desorbable surfactant to at least one surface of a printing plate substrate, (b) removing non-adsorbed surfactant from the surface, (c) applying a fluid composition containing an ink receptive material onto at least a portion of the surface in the form of a desired image, thereby providing an ink receptive image layer; and (d) removing the desorbable surfactant from any area of the surface which does not form part of the desired image.
