Abstract: A laminating apparatus is provided which causes a resin film to completely conform to protruding and recessed portions of a substrate, and which makes the film thickness of the conforming resin film uniform on a stricter level. To this end, the laminating apparatus includes a laminating mechanism including: an enclosed space forming receiver capable of receiving a provisionally laminated body therein; and a pressure laminator for applying pressure to the provisionally laminated body in non-contacting relationship in an enclosed space formed by the enclosed space forming receiver to form an end laminated body from the provisionally laminated body.

Abstract: To provide a photosensitive resin composition and a photosensitive element using the resin composition with excellent sensitivity and adhesion as well as high resolution and plating resistance. A photosensitive resin composition, comprises (A) a polymer carrying carboxyl groups, (B) a compound carrying at least one ethylene-based unsaturated group in the molecule, and (C) a photopolymerization initiator, characterized by the fact that component (B) contains at least 60 weight % of methacrylate (B1) carrying at least one ethylene-based unsaturated group with respect to the total amount of component (B), that the amount of component (C) is in the range of 0.01-20 weight units with respect to 100 weight units of component (A) and component (B), and that component (C) contains 2-5 weight units of lophine dimer (C1) and 0.1-2.0 weight units of triphenylphosphine (C2) with respect to 100 weight units of component (A) and component (B), as well as a photosensitive element using the resin composition.

Abstract: The invention provides a negative-acting photoimageable composition comprising A) between about 30 and about 80 wt % based on total weight of A) plus B) of a binder polymer having acid functionality sufficient to render said photoimageable composition developable in alkaline aqueous solution, B) between about 20 and about 70 wt % based on total weight of A) plus B) of an addition-polymerizeable, non-gaseous &agr;,&bgr;-ethylenically unsaturated compound(s) capable of forming a high polymer by free-radical initiated chain-propagating addition polymerization, at least about 50 mole percent of the &agr;,&bgr;-ethylenically unsaturated moieties of B) being methacrylic moieties, and C) between about 0.1 and about 20 wt % based on total weigh of A) plus B) of a photoinitiator chemical system. Photopolymerizable component B comprises, at between about 1 and about 70 wt. % relative to total of A) plus B) a biuret urethane oligomer having &agr;,&bgr;-ethylenic unsaturation.

Abstract: In a negative acting photoimageable composition comprising an acid functional binder polymer, photopolymerizable .alpha.,.beta.-ethylenically unsaturated compounds, and photoinitiator, at least a portion of the photopolymerizable compounds are isocyanate trimers having tri-acrylate functionality. Further, the composition contains a dibenzoate plasticizer.
