摘要： Provided is a thermosetting resin composition that has high reactivity, can be adapted to various curing conditions, and has extremely high versatility.
The thermosetting resin composition contains a resin component (A) containing -COOR (R is an alkyl group having 50 or less carbon atoms) and a hydroxy group, and a transesterification catalyst (B). A curing start temperature is 130°C or lower, and a gel fraction when cured under a condition of baking at 150°C for 30 minutes is 80% or more.-

摘要： Provided is a thermosetting resin composition, from which a cured product having excellent transparency with less yellowing than that in the related art can be obtained, and which is advantageous in cost because a monomer obtained by using an inexpensive raw material is used. An ester compound contains, in one molecule, at least one functional group represented by the following general formula (1) or (2) .
(In both the general formulae (1) and (2), R 1 is an alkyl group having 50 or less carbon atoms.
R 2 is an alkylene group having 50 or less carbon atoms that may contain an oxygen atom and a nitrogen atom as a portion thereof.)-

摘要： [Problem] To obtain a thermosetting resin composition that has curing performance at a lower temperature and uses transesterification capable of also suitably coping with conversion into an aqueous form as a curing reaction.
[Solution] A thermosetting resin composition containing a resin component (A), which includes a structure (a) represented by the following general formula (1) and a hydroxy group (b), and a transesterification catalyst (B).
n = 0 to 20
R 1 is an alkyl group having 50 or less carbon atoms.
R3 is hydrogen or an alkyl group having 10 or less carbon atoms.-

摘要： To provide a resin composition, which has both a thermosetting property and active energy curability, satisfactory performances, and excellent performances including handleability of being inexpensive without having a concern about a short pot life after blending with a thermal cross-linking agent as in the related art. The curable resin composition contains: a resin component (A) containing a (meth)acryloyl group (a), a hydroxy group (b), and an alkyl ester group (c); and an initiator (B).

摘要： Provided is a curable resin composition having high reactivity and curable at low temperatures.
The curable resin composition includes: a resin component (A) having -COOR (R is an alkyl group having 50 or less carbon atoms) and a hydroxyl group; and a transesterification catalyst (B), characterized in that the transesterification catalyst (B) contains a zinc-containing compound and an imidazole compound.
