Abstract
A UV curable, etch-resistant ink composition for ink jet printing of variable information on printed circuit boards and for printing the circuit boards themselves comprising a resin formulation having at least two acrylate components, one of which is an acrylate having a pendant carboxyl group and one of which is an acrylated epoxy monomer or dimer, a photoinitiator and an organic carrier. Also, methods for printing variable information on printed circuit boards and for printing the circuit boards themselves utilizing a UV curable, etch-resistant ink composition.
Claims41
An ink composition for use in ink jet printing comprising:
- a. a resin composition comprising at least two acrylate resin components, a first acrylate resin component being an aromatic acrylate resin that contains at least one pendant carboxyl group and a second resin acrylate component being an acrylated epoxy monomer or dimer;
- b. a photoinitiator;
- and
- c. an organic carrier.
The composition according to claim further comprising a conductivity agent.
The composition according to claim further comprising a photosensitizer.
The composition according to claim wherein said resin composition further comprises at least one acrylate resin capable of providing chemical resistance to said ink composition.
An ink composition for use in ink jet printing comprising Biphenol A epoxy diacrylate, aromatic monofunctional acrylate, nonyl phenol ethoxylate monoacrylate, Bisphenol A ethoxylate diacrylate, trimethylol propane propoxylate triacrylate, ethoxylated neopentyl glycol diacrylate, trimethylol propane triacrylate, 2-benzyl-2-N,N-dimethylamino-1-(4-morpholinophenyl)-1-butanone, methanol, methyl ethyl ketone, lithium nitriate, a fluorinated alkyl ester, 2-isopropylthioxanthone, and p-methoxyphenol.
