preparation example Construction

[0032] Appropriately synthesized products or commercially available products can be used as free-radically polymerizable compounds with hyperbranched or dendritic molecular structures. Examples of synthetic methods include the following.

[0033] Hyperbranched structures result from the self-condensation of ABx-type molecules containing a total of three or more two substituents per molecule. For example, hyperbranched polyesters are obtained by polycondensation from 3,5-dihydroxybenzoic acid as a component. In this case, the hyperbranched polyester has hydroxyl groups at the end. When acrylic acid or methacrylic acid is allowed to react with this hydroxyl group, a radically polymerizable compound having a hyperbranched structure is obtained. Known dendrimer synthesis methods include divergent methods that push synthesis outward from the core, convergent methods that push synthesis inward from terminal functional groups, and methods that combine the two methods. For example,...

[0096] The used dendrimer compounds are shown in Table 1, and the used polyester resins are shown in Table 2.

[0097] As other materials, THFA (product name: BISCOAT #150, available from Osaka Organic Chemical Industry Ltd.), IBXA (available from Osaka Organic Chemical Industry Ltd.), and TMPTA (available from Daicel-Allnex Ltd.) were used as A polymerizable monomer, OMNIRAD TPO (available from IGM Resins B.V.) was used as a polymerization initiator, and BHT (available from Tokyo Chemical Industry, Co., Ltd.) was used as a polymerization inhibitor.

Abstract

Provided is an active energy ray curable composition comprising: a polymerizable dendritic branched compound; and a polyester-based resin containing a polymerizable unsaturated bond.

Description

technical field [0001] The present disclosure relates to active energy ray-curable compositions, active energy ray-curable ink compositions, active energy ray-curable inkjet ink compositions, and two-dimensional or three-dimensional image forming methods. Background technique [0002] Active energy ray-curable compositions are cured by active energy ray irradiation and thus have better driability than solvent-based ink compositions. Active energy ray-curable compositions are required to have adhesion to inorganic base materials such as glass. [0003] For example, an inkjet ink composition containing a colorant, a polymerizable compound, a polymerization initiator, an unreacted resin, and an organic solvent has been proposed as an inkjet ink composition that can be used with a recording medium formed of a material that does not absorb ink Images were formed with improved adhesion (see, eg, PTL 1). [0004] An active energy ray-curable composition comprising at least a poly...
