Embodiment 1-

[0029] Example 1 - Plasma polymer coating

[0030] A piece of polyethylene film substrate was rinsed ultrasonically in a 1:1 mixture of isopropanol and cyclohexane and placed on a glass plate in the chamber. After removing the residual gas, with a flow rate of 1900sccm, at 1.02×10 5 N m -2 A plasma discharge gas is introduced under pressure. Two discharge gases are used: helium and a mixture of 99% helium and 1% oxygen. After purging (purging) for 10 minutes, turn on the syringe pump to make the coating forming material 3×10 -5 mls -1 "speed flow. There are two kinds of coating forming materials used, octamethylcyclotetrasiloxane and tetramethylcyclotetrasiloxane. When the coating forming material reaches the ultrasonic nozzle, the sonotrode is turned on (2.5W ) to initiate atomization of the coating-forming material, and 1.5 kV was applied between the electrodes to ignite an atmospheric pressure plasma discharge.

[0031] Deposition of the coating forming material was a...

Embodiment 2

[0032] Example 2 - Use of Radiation Curable Red Printing Ink

[0033] 40 parts of red colorant aqueous dispersion (Sunsperse RHD6012 of Sun Chemical Pigments Division), 50 parts of aliphatic epoxy acrylate (Laromer LR8765 of BASF Company), 5 parts of water, 5 parts of photoinitiator (Irgacure 2959 of Ciba Company) )Mix together. The mixture was coated on a plasma polymer coated substrate with a flexographic hand proofer and cured by UV radiation.

Embodiment 3

[0034] Example 3 - Use of radiation curable blue printing ink

[0035] Put 30 parts of Pigment Blue 15:3 (Phthalocyanine Blue from Sun Chemical Company) and 70 parts of highly ethoxylated trimethylolpropane triacrylate (15 moles EO, SR9035 from Sartomer Company) on a three-roll mill Grind to form a 2 / 0 grind concentrate base. Mix 20 parts of base material with 40 parts of polyethylene glycol (400) diacrylate (SR344 of Sartomer Company), 10 parts of photoinitiator (Irgacure 2959 of Ciba Company), 10 parts of highly ethoxylated trimethylol Propane triacrylate (15 moles EO, SR9035 from Sartomer) and 40 parts water were mixed together to form a blue ink. The ink was applied to the plasma polymer coated substrate of Example 1 using a flexographic hand proofer and cured with UV radiation.

Abstract

A plasma polymer having residual functional (reactive) groups is formed on a substrate, a radiation curable coating composition is applied to the plasma polymer-coated substrate, and the radiation curable composition is radiation cured. The radiation curable composition contains a component which forms a polymer with the reactive groups of the plasma polymer, anchoring the cured composition to the plasma polymer which is anchored to the substrate.

Description

[0001] The present disclosure is entitled to the benefit of priority of US Provisional Application Serial No. 60 / 529,382, filed December 16, 2003. Background of the invention [0002] The present invention relates to a method of forming a radiation curable coating on a substrate, in particular for forming an ultraviolet (UV) ink coating or an electron beam (EB) ink coating on a substrate, the invention also relates to such The resulting coated product. [0003] Radiation-curable coatings, including inks, have been developed for a variety of applications. Broadly speaking, coating compositions comprise radiation curable monomers or prepolymers together with suitable viscosity control agents, antioxidants, polymerization inhibitors, polymerization catalysts, surfactants, etc. to obtain the desired properties. One problem encountered with such systems is adhesion to the substrate being coated and various systems have been developed to improve adhesion. While achieving better ad...
