Abstract
The invention provides curable ink compositions that are inkjet printable and that adhere to a variety of substrates, for example, glass and polymer. The ink compositions of the invention can be formulated so to provide cured inks that are very flexible or very rigid depending upon the desired application. The invention provides a cure-on-demand curable ink composition including a homogeneous mixture of at least one of: (a) a compound having 2 reactive silyl groups, and (b) a compound having at least 3 reactive silyl groups; acid generating catalyst; and pigment or pigment chip. The invention also provides methods of making and using the ink compositions and imaged articles.
