Provided is a curable resin composition, wherein the content of the thermoplastic resin (A) is 42% by weight or more based on the total resin content of the curable resin composition.
熱可塑性樹脂(A)としては加熱により軟化する樹脂高分子であれば特に限定されない。熱可塑性樹脂(A)のガラス転移温度は特に限定されないが、その下限値は、例えば、-120℃が好ましく、より好ましくは60℃、さらに好ましくは100℃であり、上限値は、例えば、200℃が好ましく、より好ましくは140℃、さらに好ましくは110℃である。下限値が上記範囲であることにより塗膜乾燥後のタックフリー性が優れる傾向がある。また、上限値が上記範囲であることにより硬化性樹脂組成物の取り扱いが優れる傾向がある。なお、ガラス転移温度は示差走査熱量計(DSC)法により測定したものである。 [Thermoplastic resin (A)]
The thermoplastic resin (A) is not particularly limited as long as it is a resin polymer that is softened by heating. The glass transition temperature of the thermoplastic resin (A) is not particularly limited, but the lower limit is, for example, preferably −120 ° C., more preferably 60 ° C., further preferably 100 ° C., and the upper limit is, for example, 200 ° C is preferred, more preferably 140 ° C, and even more preferably 110 ° C. When the lower limit is in the above range, the tack-free property after drying the coating tends to be excellent. Moreover, there exists a tendency for the handling of curable resin composition to be excellent because an upper limit is the said range. The glass transition temperature is measured by a differential scanning calorimeter (DSC) method.
(メタ)アクリロイル基を5以上有する樹脂(B)としては特に限定されないが、例えば、ジペンタエリスリトールペンタ(メタ)アクリレート、ジペンタエリスリトールヘキサ(メタ)アクリレート、トリペンタエリスリトールペンタ(メタ)アクリレート、トリペンタエリスリトールヘキサ(メタ)アクリレート、トリペンタエリスリトールヘプタ(メタ)アクリレート、及びトリペンタエリスリトールオクタ(メタ)アクリレート等の(メタ)アクリロイル基を5以上有する低分子(例えば、分子量が200~800)化合物、(メタ)アクリロイル基を5以上有するシリコーン(メタ)アクリレート、(メタ)アクリロイル基を5以上有するウレタン(メタ)アクリレートが挙げられる。これらは、1種を単独で使用することもできるし、2種以上を組み合わせて使用することもできる。 [Resin (B) having 5 or more (meth) acryloyl groups]

These can also be used individually by 1 type and can also be used in combination of 2 or more type.
(4×0.6+6×0.4)/(0.6+0.4)=4.8 The silicone (meth) acrylate may be a mixture of two or more of the same or different average functional group numbers. The average functional group number of the mixture can also be determined by weighted average. For example, in the case of a mixture of 0.6 mol of silicone (meth) acrylate having an average number of functional groups of 4 and 0.4 mol of silicone (meth) acrylate having an average number of functional groups of 6, the average number of functional groups of silicone (meth) acrylate is , Which can be calculated according to the following formula: 4.8.
(4 × 0.6 + 6 × 0.4) / (0.6 + 0.4) = 4.8

例えば、1,3-ブタンジオール1モルと、1,6-ヘキサンジイソシアネート2モルと、2-ヒドロキシエチル(メタ)アクリレート1モル及びペンタエリスリトールトリ(メタ)アクリレート1モルの混合物とを反応させた場合が上記に該当する。なお、前記モノマーのモル比は、1:2:1:1である。 Here, the “average (meth) acryloyl group number” is an average value of the number of (meth) acryloyl groups per molecule of urethane (meth) acrylate. For example, 1 mol of diol (X1) as polyol (X), 2 mol of diisocyanate (Y1) as polyisocyanate (Y), one hydroxy group and one hydroxyl group-containing (meth) acrylate (Z) Average of urethane (meth) acrylate obtained when 1 mol of compound (Z1) having (meth) acryloyl group and 1 mol of compound (Z2) having 3 (meth) acryloyl groups are reacted with 1 mol The number of (meth) acryloyl groups is 4 (the structure of the resulting urethane (meth) acrylate is schematically shown below).
(Z1)-(Y1)-(X1)-(Y1)-(Z2)
For example, when 1 mol of 1,3-butanediol, 2 mol of 1,6-hexane diisocyanate, 1 mol of 2-hydroxyethyl (meth) acrylate and 1 mol of pentaerythritol tri (meth) acrylate are reacted. Corresponds to the above. The molar ratio of the monomers is 1: 2: 1: 1.
(2×0.4+4×0.6)/(0.4+0.6)=3.2 The urethane (meth) acrylate may be a mixture of two or more of the same or different average functional groups. The average functional group number of the mixture can also be determined by weighted average. For example, when it is a mixture of urethane (meth) acrylate 0.4 mol having an average functional group number of 2 and urethane (meth) acrylate 0.6 mol having an average functional group number 4, the average functional group number of urethane (meth) acrylate Can be calculated according to the following equation: 3.2.
