摘要:
An aqueous composition is essentially free of organic solvents, plasticizers and additional tackifiers and contains water and 20-99% by weight of a polymer and 1-80% by weight of a filler, the percentages by weight being based on the sum of the components of the aqueous composition, with the exception of water.
摘要:
Readily filterable and deodorizable aqueous dispersions of pressure-sensitive adhesive, especially for self-adhesive labels, having solids contents of more than 65%, can be prepared with readily reproducible properties by copolymerizing esters of acrylic and/or methacrylic acid in the presence of less than 50 ppm of inhibitor and, preferably, in the presence of from 0.01 to 5% by weight of reducing agent by a special emulsion technique. The highly concentrated pressure-sensitive adhesive dispersion, subsequently deodorized with steam, is free from coagulum and seediness.
摘要:
The present invention relates to the use of at least one radiation crosslinkable, preferably UV crosslinkable, polymer composition as a data recording medium, especially in the form of what are known as smart coatings based on such polymer compositions, which in a further embodiment comprises at least one fluorescence chromophore, and also to a composite at least comprising one support and one layer comprising a radiation crosslinkable polymer composition comprising at least one fluorescence chromophore, and also, preferably, an additional UV absorbing layer.
