Ink-jet print head comprising a layer made by a curable resin composition |
摘要 |
The present invention relates to an ink-jet print head able to resist to chemically aggressive solvent-based inks, and to a process for the manufacturing thereof, the ink-jet print head comprising a polymeric material layer defining ink passage ways formed on a substrate, said polymeric material layer being formed by curing a curable resin composition comprising a cyclic aromatic di-functional epoxy resin, a cyclic aliphatic di-functional epoxy resin and a polymerization initiator. The invention also relates to an improved curable resin composition. |

1. An ink-jet print head comprising a polymeric material layer defining ink passageways formed on a substrate, said polymeric material layer being formed by curing a curable resin composition comprising:
(a) a cyclic aromatic di-functional epoxy resin obtained by the condensation of bisphenol A and epichlorohydrin having an epoxide equivalent weight (EEW) of at least 400 g/eq., (b) a cyclic aliphatic difunctional epoxy resin represented by the following formula: wherein R is a carboxyalkylene group of formula —(CH2)p—COO— or —(CH2)q—COO—(CH2)r—OCC—(CH2)s— and p, q, r, and s each independently is an integer of from 1 to 9, and (c) a polymerization initiator. |
