Abstract: The objective of the present invention is to provides a cationically curable epoxy resin composition excellent in sealing and adhesive property specifically to glass, excellent reflow resistance property, moisture resistance and water resistance while keeping a good workability intrinsic to a light curable resins. The invention provides a cationically curable epoxy resin composition comprising: (a) an epoxy resin component; (b) a cationic photo-initiator; (c) a cationic thermal-initiator and (d) a filler selected from the group consisting of oxides, hydroxides and carbonates containing a Group II element in the long periodic table.

Abstract: The present invention provides a cationically photocurable epoxy resin composition, which contains (a) an epoxy resin component comprising an alicyclic epoxy resin and an aromatic-ring containing epoxy resin, (b) a cationic photoinitiator component, and (c) a filler selected from oxides, hydroxides and carbonates containing a Group II element. This composition exhibits improved adhesive strength to a glass such as an alkali glass, particularly a sodium-containing glass, or a metal.

Abstract: The present invention relates to a near infrared ray-decolorizable recording material comprising a near infrared ray-absorbing cationic dye-borate anion complex having the formula (I): ##STR1## wherein D.sup.+ represents a cationic dye having absorptions in the near infrared region; R.sub.1, R.sub.2, R.sub.3, and R.sub.4 independently represent an alkyl, aryl, alkaryl, allyl, aralkyl, alkenyl, alkynyl, silyl, alicyclic, or saturated or unsaturated heterocyclic group, substituted alkyl, substituted aryl, substituted alkaryl, substituted allyl, substituted aralkyl, substituted alkenyl, substituted alkynyl, or substituted silyl, with the proviso that at least one of R.sub.1, R.sub.2, R.sub.3, and R.sub.4 represents an alkyl group having 1 to 8 carbon atoms.
