- the present invention is a photocurable composition containing a (meth) acrylic copolymer (A) containing a macromonomer as a structural unit, a crosslinking agent (B), and a crosslinking initiator (C), and a small-angle X-ray

- the photocurable composition proposed by the present invention it is possible to exhibit self-adhesiveness (referred to as “tackiness”) while maintaining a sheet shape at room temperature, and when heated in an uncrosslinked state, it softens or flows. For example, it can be softened or flowed by being heated to a temperature higher than the glass transition temperature of the macromonomer, and can be filled up to every corner following the uneven portion of the bonding surface. Furthermore, since excellent cohesive force can be exhibited by photocuring, adherends can be firmly bonded to each other.
- the composition according to an example of the embodiment of the present invention includes a (meth) acrylic copolymer (A) containing a macromonomer as a structural unit, and a crosslinking agent (B). And a cross-linking initiator (C), wherein the half-value width X1 (nm ⁇ 1 ) of the one-dimensional scattering profile in the small-angle X-ray scattering measurement is 0.05 ⁇ X1 ⁇ 0.30 It is a photocurable composition characterized by these.
- the above-mentioned “contains a macromonomer as a structural unit” means that a (meth) acrylic copolymer (A) is included in addition to a case where a macromonomer is included as a copolymer component of the (meth) acrylic copolymer (A). This includes the case where it is contained as a structural unit other than the copolymer component, such as when it is contained as an additional bond component.
- This photocurable composition has a structure in which at least one of the crosslinking agent (B) and the crosslinking initiator (C) is bonded to the (meth) acrylic copolymer (A). Is preferred.

Furthermore, if at least one of the crosslinking agent (B) and the crosslinking initiator (C) is bonded to the (meth) acrylic copolymer (A), the (meth) acrylic copolymer (A) is crosslinked. Since it is possible to intentionally design the location to be performed, it becomes easy to control the half width of the one-dimensional scattering profile in the small-angle X-ray scattering measurement defined in the present invention.
- the term “bonded to the (meth) acrylic copolymer (A)” means that the crosslinking agent (B) or the crosslinking initiator (C) and the (meth) acrylic copolymer (A) Refers to a state in which is bound by a chemical bond including a covalent bond, an ionic bond and a metal bond.
- this photocurable composition is characterized in that the half width X1 (nm ⁇ 1 ) of the one-dimensional scattering profile in the small-angle X-ray scattering measurement is 0.05 ⁇ X1 ⁇ 0.30.
- the small-angle X-ray scattering measurement is a technique for obtaining nanoscale (1 to 100 nm) structural information by observing scattered X-rays having a scattering angle of several degrees or less (specifically, for example, 10 ° or less). Therefore, a composition in which a one-dimensional scattering profile can be observed in small-angle X-ray scattering measurement means that the composition is not in a state where a one-dimensional scattering profile is not observed in small-angle X-ray scattering measurement.
- the shape and state of the present photocurable composition are not limited.
- the (meth) acrylic copolymer (A) in the present photocurable composition is a copolymer containing a macromonomer as a structural unit.
- a copolymer having a macromonomer as a structural unit forms a graft copolymer or a block copolymer.
- the graft copolymer is usually formed by addition, condensation or copolymerization with another monomer.
- the block monomer is usually formed by addition, condensation or copolymerization with other monomers.
- a graft copolymer or a block copolymer forms a (micro) phase separation structure.
- the half width of the one-dimensional scattering profile in the small-angle X-ray scattering measurement for the present photocurable composition is defined by the composition containing the (meth) acrylic copolymer (A) as described above (micro). It can be considered as a measure of the “phase separation state” of the phase separation structure. That is, for example, the trunk component and the branch component in the graft copolymer, or the individual block components in the block copolymer form a microscopically separated state as different “phases”.
- the half-value width of the one-dimensional scattering profile in the small-angle X-ray scattering measurement is large (wide), it means that the peak is broad, and each phase separated as compared with the case where the half-value width is small. This means that the density difference between phases is small or the phase separation structure is not uniform.
- the smaller (narrower) the half-value width means that the peak is sharper.
- the density difference of each phase that is phase-separated is clearer or the phase separation structure is It means more uniform. Therefore, in the present photocurable composition, by controlling the half width within a specific range, each phase phase-separated microscopically can separately bear different adhesive properties. Therefore, it can be considered that it has become possible to combine characteristics that are generally difficult to achieve.
- each block component (for example, “block component”).
- Component A ”and“ Block component B ”) may be read.
- the half-value width X1 of the one-dimensional scattering profile in the small-angle X-ray scattering measurement is such that the branching component composed of the macromonomer in the copolymer containing the macromonomer as a constituent unit
- the (micro) phase separation structure formed with the trunk component can be used as an indicator of the state after changing depending on the crosslinking agent or photoinitiator to be formulated.
- the conventionally disclosed photocurable composition as described above that is, a macromonomer is included as a structural unit (meta )
- a macromonomer is included as a structural unit (meta )
