Description

  The present invention relates to a photopolymerizable composition that is cured by irradiation with energy such as ultraviolet rays, light, or an electron beam.

  Resins that are cured by irradiation with energy such as ultraviolet rays and electron beams are used in various industrial fields. For example, a resin that is cured by light irradiation is used for manufacturing an electronic device as a material for lithography. In recent years, the structure of electronic devices has been further miniaturized, and further improvement in processing accuracy has been demanded in lithography technology using a photocurable resin.

  Conventionally, a photopolymerizable composition used for photolithography starts a photochemical reaction with a polymer resin (prepolymer) that causes a photochemical reaction and a polymerizable low molecule (monomer) as a diluent for the prepolymer. For example (see Patent Documents 1 to 3).

Prepolymers include acrylic acid / 1,6-hexanediol / acrylic acid (formula 1), phthalic anhydride / propylene oxide / acrylic acid (formula 2), trimellitic acid / diethylene glycol / acrylic acid (formula 3 Polyester-based ultraviolet curable resins having a relatively large molecular weight such as

  However, since the prepolymer has a very high viscosity and is difficult to handle such as coating, a polyfunctional monomer copolymerizable with the prepolymer is often added as a diluent. This diluent has a lower molecular weight than the prepolymer, and the viscosity can be lowered by adding it to the prepolymer. Although it is possible to reduce the viscosity by diluting the prepolymer with a solvent, this causes the solvent to volatilize before light irradiation, resulting in irregularities on the surface, which reduces the processing accuracy in photocuring. Problems arise. Further, when the prepolymer is diluted with a solvent, the viscosity changes due to volatilization of the solvent, and handling becomes difficult.

  For this reason, the present inventors have already developed a polymerizable dendritic polymer in which a polymerizable carbon-carbon double bond or an epoxy group is modified at the end of a dendritic polymer having a unique branched structure. (Patent Document 4 and Patent Document 5). These polymerizable dendritic polymers have the property of having a small viscosity for having a large molecular weight. By using this as a prepolymer, a photopolymerizable composition that has a low viscosity and is easy to handle. It becomes.

As a technique related to the present invention, Patent Document 6 describes a method for producing a highly branched polymer in which glycidol is polymerized in a branched form.

  However, the polymerizable dendritic polymers described in Patent Documents 4 and 5 are produced by extending the branched structure step by step, so that the number of production steps is large and time-consuming, and the production cost increases. was there. The present invention has been made in view of such conventional circumstances, and solves the problem of providing a photopolymerizable composition that has low viscosity and is easy to handle, easy to manufacture and can be manufactured at low cost. It is an issue that should be done.

  For dendritic polymers with a highly branched structure, a dendrimer formed by the chemical reaction of a monomer with a polyfunctional group step by step and an ABx type monomer are polycondensed to form a branched structure at once. Hyperbranched polymers are known. The polymerizable dendritic polymer described in Patent Documents 4 and 5 is a dendrimer. The inventors have used the above-mentioned conventional problem by using a polymerizable hyperbranched polymer obtained by modifying a polymerizable functional group in a hyperbranched polymer that is easy to produce instead of a dendrimer as a polymerizable component of an optical resin composition. The present invention was completed as a result of diligent research on the idea that the problem could be solved.

  That is, the photopolymerizable composition of the first invention in the present invention is a glycidyl ether having a carbon-carbon double bond capable of polymerizing a terminal hydroxyl group of a highly branched polymer in which glycidol is polymerized in a branched manner starting from the hydroxyl group of the core molecule. It comprises a polymerizable hyperbranched polymer added to the epoxy group, a polymerizable monomer capable of binding to the polymerizable hyperbranched polymer, and a photopolymerization initiator.

  The photopolymerizable composition of the first invention includes a polymerizable hyperbranched polymer modified with a polymerizable carbon-carbon double bond, and a polymerizable monomer capable of binding to the polymerizable hyperbranched polymer. Further, a photopolymerization initiator is included. For this reason, when this photopolymerizable composition is irradiated with energy such as ultraviolet rays, visible rays, and electron beams, a polymerization initiator such as a radical or a cation is generated from the photopolymerization initiator, and a highly branched polymer and a polymerizable monomer are generated. And further, the polymerizable monomers are polymerized and cured. For this reason, it can be used for printing a pattern for forming an integrated circuit.

The polymerizable hyperbranched polymer contained in the photopolymerizable composition of the first invention is a highly branched polymer because the glycidol is polymerized in a branched manner with the hydroxyl group of the core molecule as a base point. Although it has a large molecular weight, it has the property of low viscosity. For this reason, compared with the photopolymerizable composition containing a prepolymer, a viscosity is small and handling is easy, and the precision at the time of printing can also be improved.
In addition, since the polymerizable highly branched polymer can form a branched structure at a stretch by polycondensing monomers, the number of manufacturing steps is small, the synthesis is easy, and the manufacturing cost can be reduced.

  The polymerizable monomer may be any compound that can be bonded to the polymerizable hyperbranched polymer, and includes an oligomer in which several monomers are bonded. As the polymerizable monomer, an acrylic monomer having one or more (meth) acryl groups per molecule can be used.

Acetophenone, benzophenone, benzyl, benzoin, benzoin isobutyl ether, benzyl dimethyl ketal, tetramethyl thiuram sulfide, azobisisobutyronitrile, benzoyl peroxide, and the like. Moreover, it is also preferable to use the photoradical generator of following Chemical formula (4) and Chemical formula (5). Since these photoradical generators generate radicals efficiently even for light with low intensity, a highly sensitive photopolymerizable resin composition can be obtained.

  Moreover, as a polymerizable monomer, the epoxy-type monomer which has one or more epoxy groups in 1 molecule can also be used. Specifically, 3,4-epoxycyclohexylmethyl 3,4-epoxycyclohexanecarboxylate, 2,2-bis (4-glycidyloxyphenyl) propane, bisphenol A propoxylate diglycidyl ether, bisphenol F diglycidyl ether, glycerol Diglycidyl ether, glycerol propoxylate triglycidyl ether, 3-glycidoxypropyldimethoxymethylsilane, 3-glycidoxypropyldimethylethoxysilane, ethylene glycol diglycidyl ether, diethylene glycol diglycidyl ether, diglycidyl 1,2-cyclohexanedicarboxy Rate, polyethylene glycol diglycidyl ether, 1,3-butanediol diglycidyl ether, 1,4-butanediol diglycidyl ether, 1,4-cyclohexane Methanol diglycidyl ether, N, N-diglycidyl aniline, N, N-diglycidyl-4-glycidyl oxyaniline, neopentyl glycol diglycidyl ether, poly (dimethylsiloxane) diglycidyl ether, poly (propylene glycol) diglycidyl ether, Resorcinol diglycidyl ether, trimethylolethane triglycidyl ether, trimethylolpropane triglycidyl ether and the like can be mentioned. In addition, Poly [(phenyl glycidyl ether) -co-formaldehyde] (Poly [(phenyl glycidyl ether) -co-formaldehyde), Poly (bisphenol A-co-epichlorohydrin), glycidyl end-caped (Poly (bisphenol A-co-formaldehyde)) Epichlorohydrin, glycidyl endcapped), etc. Poly [(phenyl glycidyl ether) -co-formaldehyde] (Poly [(phenyl glycidyl ether) -co-formaldehyde) or Poly (bisphenol A-co-) epichlorohydrin), glycidyl end-caped (poly (bisphenol A-co-epichlorohydrin), glycidyl end-capped), etc. The inventors have used 3,4-epoxycyclohexylmethyl 3,4 as epoxy-based monomers. The photopolymerizable composition using 4-epoxycyclohexanecarboxylate and 2,2-bis (4-glycidyloxyphenyl) propane ensures that a cross-linked product is obtained by light irradiation. It is confirmed that

  The photopolymerization initiator is preferably a photoacid generator that generates an acid by light irradiation. Examples of such a photoacid generator include [4-[(2-hydroxytetradecyl) oxy] phenyl] phenyliodonium hexafluoroantimonate, bis (4-tert-butylphenyl) iodonium perfluoro-1-butanesulfonate.
