摘要： The present invention aims to provide a lining composition which overcomes the problems such as environmental problems (e.g. marine pollution) and VOC problem and which has a good cure rate. We have found that this can be achieved by a composition containing a vinyl ester resin as a prepolymer component and an aliphatic or alicyclic polyfunctional allyl ester compound as a crosslinking agent.

摘要： The present invention provides silver nanoparticles that form a sintered body having a high shear strength and a low specific resistance when sintered at a low temperature (for example, 200° C. or less), even though the silver nanoparticles have an average particle diameter as large as 200 nm or more. Silver nanoparticles having an average particle diameter of 200 to 600 nm, wherein an exothermic peak due to binding of the silver nanoparticles in thermogravimetry-differential thermal analysis appears at less than 175° C., and a weight loss on heating from 30 to 500° C. by thermogravimetry-differential thermal analysis is 0.4% by weight or less.

摘要： Provided is an electroconductive adhesive which is less apt to suffer cracking, chipping, etc. upon sintering and gives sintered objects having excellent mechanical strength. The electroconductive adhesive comprises metallic microparticles which include a protective layer comprising one or more amines and have an average particle diameter of 30-300 nm, the amines comprising a C5-7 monoalkylamine and/or an alkoxyamine represented by the following general formula (1). NH2—R2—O—R1 (1) In the protective layer, the ratio of the C5-7 monoalkylamine and/or alkoxyamine represented by the general formula (1) to one or more amines different therefrom is in the range of 100:0 to 10:90. [In formula (1), R1 represents a C1-4 alkyl group and R2 represents a C1-4 alkylene group.]

摘要： The objection of the present invention is to provide a photocurable resin composition having deep curability. The photocurable resin composition comprises an allyl polymer (a) produced by polymerization of an allyl compound represented by the following formula (1), a photocurable compound (b), and a photopolymerization initiator (c). In the formula, n represents an integer of 2 to 4; Z is selected from a binding site, an n-valent aliphatic chain hydrocarbon group optionally having a hydroxyl group, an n-valent alicyclic hydrocarbon group optionally having an alkyl group, and an n-valent aromatic hydrocarbon group optionally having an alkyl group; n is 2 and two —COOCH2CH═CH2 moieties are directly bonded to each other when Z is a binding site.
