| 摘要 |
The invention is directed to a photoimageable composition comprising:
(I) finely divided particles of inorganic material comprising:
(a) functional phase particles selected from electrically conductive, resistive, and dielectric particles;
(b) inorganic binder having a glass transition temperature in the range of from 325 to 600°C, a surface area of no greater than 10 m 2 /g and at least 85 wt. % of the particles having a size of 0.1-10 µm;
dispersed in:
(II) an organic medium comprising:
(a) aqueous developable polymer which is a copolymer, interpolymer or mixture thereof, wherein each copolymer or interpolymer comprises (1) a nonacidic comonomer comprising a C 1-10 alkyl acrylate, C 1-10 alkyl methacrylate, styrenes, substituted styrenes or combinations thereof and (2) an acidic comonomer comprising ethylenically unsaturated carboxylic acid containing moiety;
(g) cationically polymerizable monomer;
(h) photoinitiation system; and
(i) organic solvent. |
