摘要:
The present invention relates to a method of coating substrates, including the following steps: a. applying a flowable coating composition to the target substrate and b. curing the resulting wet coating by exposure to high energy radiation, wherein said coating composition comprises as binder a polymer A containing less than 1 mol/(kg of polymer A) of reactive groups, selected from ethylenically unsaturated double bonds and epoxy groups, and at least 2 mol/(kg of polymer A) of functional groups of the formula where Y is N—H or oxygen.
摘要:
Improved cholesteric special-effect layers are obtainable by comminuting cholesteric layers. These cholesteric layers are produced by applying at least one layer of a reactive, pourable cholesteric mixture to a moving substrate, by casting, and forming a solid cholesteric layer.
摘要:
A process for coating or printing substrates with a coating or printing composition comprises applying a polymerizable material containing liquid-crystalline, polymerizable monomers which carry at least two polymerizable groups for coating and at least one polymerizable group for printing, to the substrate, and subsequently carrying out the polymerization, where the coating composition or the printing composition comprises a.sub.1) a chiral liquid-crystalline monomer and b) a polymeric binder and/or monomeric compounds which can be converted into the polymeric binder by polymerization, or, in the case of emulsion coatings and printing inks, a dispersion auxiliary d), or the coating composition or the printing composition comprises a.sub.2) an achiral liquid-crystalline monomer, b) a polymeric binder and/or monomeric compounds which can be converted into the polymeric binder by polymerization, or, in the case of emulsion coatings and printing inks, a dispersion auxiliary d), and c) a non-liquid-crystalline chiral compound.
摘要:
A process is disclosed for producing moldings, in which a pigmented coating composition (P) and a free-radically crosslinkable coating composition (K), which after crosslinking to completion produces a transparent coating (KE) are applied to a support sheet, wherein a dried but as yet not completely crosslinked coating (KT) is produced from the coating composition (K), the coated support sheet is shaped and is injection backmolded or foam-backed, and the coating (KT) is cured or aftercured; the crosslinkable coating composition (K) comprising a free-radically crosslinkable component (KK) which contains hydrogen bond forming structural elements.
