The present invention relates to a coating composition for polyester film capable of printing on all types of printers with liquid and dry toners. The coating composition comprising of a combination of polyethylene carboxylic acid dispersion and homopolymer or copolymer of polyacrylate dispersion and/or homopolymer or copolymer of polyvinyl acetate dispersion, wherein acrylate and/or acetate content be is in the range of 1 to 50% of carboxylic acid content in the dispersion.

A method of forming a digital print on a surface by applying powder of dry ink including colourants on the surface, bonding a part of the dry ink powder to the surface by a digital heating print head such that the digital print is formed by the bonded dry ink colourants and removing non-bonded dry ink from the surface.

An apparatus and methods for using coatings for metal applications are disclosed. According to one embodiment, an article comprises a cured polymeric film having a first reaction product of a cationic photoinitiator and a compound suitable for cationic polymerization. The article has a second reaction product of a free-radical photoinitiator and a compound suitable for free-radical polymerization; The article has a metal substrate, wherein the cured polymeric film coats the metal substrate.

Low reflection articles, and related systems and methods are disclosed. The articles have a surface with primary pores and secondary pores. At least some of the secondary pores contain agent, such, for example, a light absorbing dye.

A method of forming a digital print on a surface (2) by applying powder of dry ink (15) including colourants (7) on the surface, bonding a part of the dry ink (15) powder to the surface (2) by a digital heating print head (80) such that the digital print is formed by the bonded dry ink colourants (7) and removing non-bonded dry ink (15) from the surface (2).

A method of forming a digital print on a surface by applying powder of dry ink including colourants on the surface, bonding a part of the dry ink powder to the surface by a digital heating print head such that the digital print is formed by the bonded dry ink colourants and removing non-bonded dry ink from the surface.

A method of forming a digital embossing on a surface by bonding hard press particles to a carrier. A liquid binder pattern is applied on the carrier by a digital drop application head. Hard press particles are applied on the carrier and the binder pattern such that some hard press particles are bonded to the carrier by the liquid pattern and non-bonded press particles are removed. The carrier with the bonded hard press particles is pressed to the surface and an embossing is formed when the carrier with the hard press particles is removed.

In one embodiment, a method of forming an extruded board includes mixing a resin and a foaming agent, melting the mixed resin and foaming agent to form a uniformly colored extrudate, differentially expanding voids formed from the foaming agent within the uniformly colored extrudate by passing the uniformly colored extrudate through a breaker plate, forming a board with the differentially expanded voids and uniformly colored extrudate, and forming lightened portions on an outermost surface of the formed board.

Low reflection articles, and related systems and methods are disclosed. The articles have a surface with primary pores and secondary pores. At least some of the secondary pores contain agent, such, for example, a light absorbing dye.

A laser-marked polymer workpiece is described. The workpiece has a transparent component and an opaque component applied to at least one region of the transparent component. A mark is introduced onto a surface of the opaque component facing the transparent component with at least one laser. The mark is introduced, via a laser, through the transparent component. The mark is a lightening of the surface of the opaque component on which the mark was introduced.
