Abstract
An ink composition suitable for use in ink jet printing systems and for printing onto glazed ceramic surfaces in which the ink composition is formulated of a soluble, linear, low molecular weight novolac resin, a water and alcohol soluble dyestuff, an organo silicon compound having an organic group attached to the silicon atom containing a highly functional (amino) group, and a diluent of alcohol or alcohol and water in which the components are soluble.
Claims14
An ink composition in which the binder component consists essentially of a soluble, linear, low molecular weight novolac resin, and in which the diluent consists essentially of a low boiling alcohol or alcohol and water in which the amount of water does not exceed 50% and which includes a water and alcohol soluble dyestuff, an organo silicon compound in the form of a silane or its hydrolysis product in which the silane has the general formula R.sub.n SiX.sub.4-n in which X is a highly hydrolyzable group, n is a number of from 1 to 3, R is an organic group in which at least one of the groups is an organic group containing a highly functional group.
