Proposed is a flame-retardant heat-curable flowable epoxy resin composition suitable for use in case potting of film capacitors exhibiting very little settling of the particulate ingredients in storage and excellent impregnability in case potting as well as excellent flame retardancy, moisture resistance and tracking resistance of the composition after curing. The composition comprises, as a uniform blend:

Flame-retardant epoxy resin composition for case potting of film

A photocurable ink composition for forming patterns resistive to electroless plating is disclosed which includes (a) an epoxy resin, (b) an aliphatic polyol polyglycidyl ether as a reactive, viscosity controlling agent, (c) a photopolymerization catalyst, and (d) hydrophobic silica particles as a thixotropic agent.

Electroless plating-resisting ink composition

A thermosetting resin composition suitable for forming an insulating layer to be interposed between two adjacent wiring patterns of a multilayer printed wiring board is disclosed which includes a bisphenol AD epoxy resin, an aromatic polyamine, mica having an average particle size of 50 .mu.m or less, and silica having an average particle size of 20 .mu.m or less, the average particle size of the silica being smaller than that of the mica, and the amount of the silica being 20-80% based on the total weight of the silica and the mica.

Epoxy resin composition and multilayer printed wiring board having

An epoxy resin composition suitable for use as a casting resin for the potting of an ignition coil is disclosed which comprises:

Epoxy resin composition based on bisphenol epoxy, polyetherpolyol,

A conducting layer such as an additional wiring pattern or an electromagnetic insulation layer is formed on a conducting surface such as of a printed circuit board with an insulating layer being interposed therebetween, by a method which includes the steps of:
