Abstract
A composition of a release coating, for furnishing a release liner with a layer of the release coating, has a release agent and 0.01% by weight to 30% by weight (based on the overall composition) of a finely particulate additive in the form of three-dimensional bodies based on polymers prepared from vinyl building blocks.
Claims16
A composition of a release coating comprising:
- a release agent;
- and
- 0.01% by weight to 30% by weight, based on a total composition, of a finely particulate additive in a form of three-dimensional bodies based on polymers prepared from vinyl building blocks, wherein the three-dimensional bodies consist of solid material consisting of polymethyl methacrylate or mixtures of polymethyl methacrylate, wherein a minor length of a minor diameter of the three-dimensional bodies differs by not more than 20% from a major length of major diameter of the three-dimensional bodies.
A release liner comprising a backing film and a solvent-containing release coating, wherein the backing film is selected from the group consisting of biaxially oriented polyethylene terephalate, polybutene, polypropylene, polyethylene, monoaxially oriented polypropylene, biaxially oriented polypropylene and polyethylene, wherein the solvent-containing release coating comprises:
- a release agent;
- and
- 1 to 8 wt %, based on a total weight of the solvent-containing release coating, of a finely particulate additive in a form of three-dimensional bodies based on polymers prepared from vinyl building blocks, wherein the three-dimensional bodies consist of solid material consisting of polymethyl methacrylate or mixtures of polymethyl methacrylate, wherein a minor length of a minor diameter of the three-dimensional bodies differs by not more than 20% from a major length of a major diameter of the three-dimensional bodies.
