The present disclosure provides a method of making an article particularly a dental article having a desired color, the method comprising the steps of: (a) providing a color array, said array comprising a plurality of distinct color points, each color point being independently composed of a resin mixture comprising one or more master batch resins; (b) comparing the desired color with the color points on the color array and selecting a color point that substantially corresponds to the desired color of the article; (c) identifying the resin mixture corresponding to said selected color point; and (d) making the article using said identified resin mixture. The embodiments include the preparation of master batch resins comprising mainly bisphenol A dimethacrylate, polyethylene glycol) di acrylate, tetrahydrofurfuryl methacrylate, phenylbis(2,4,6 trimethyl benzoyl)phosphine oxide and 2,5-bis(5-tert-butyl-benzoxazol-2-yl)thiophene, as well as the preparation of 36-color array by mixing the master batch resins at different ratios.

An adhesive exhibits superior adhesive strength on adhesive-resistant materials such as olefin elastomer substrates when cured at a comparatively high temperature of 35 DEG C, and is hot water resistant. A two-pack adhesive comprises (A) a primary agent containing (1) isobornyl methacrylate and (2) at least one type of monocyclic methacrylate selected from a group including phenoxyethyl methacrylate, tetrahydrofurfuryl methacrylate, and cyclohexyl methacrylate, and (B) an initiator containing an organoborane, with the adhesive containing from 40 to 200 parts by mass of the monocyclic methacrylate per 100 parts by mass isobornyl methacrylate.

The invention discloses an acrylic structural adhesive bonded to an aluminum shell of a flame-retardant power battery, which comprises an oxidizing agent component and a reducing agent component, and the volume ratio of the oxidizing agent component and the reducing agent component is 1:1; the oxidizing agent component Including isobornyl methacrylate, 2-phenoxyethyl acrylate, 3,3,5-trimethylcycloethane methacrylate, nitrile rubber, methyl methacrylate-butyl acrylate Block copolymers, flame retardants, peroxides and stabilizers; reducing agent components include tetrahydrofurfuryl methacrylate, isooctyl methacrylate, 2‑hydroxyethyl methacrylate phosphate, terminal Carboxyl-modified neoprene, methyl methacrylate-butyl acrylate diblock copolymer, flame retardant, substituted thiourea, cobalt naphthenate, additives and stabilizers. The invention also discloses a preparation method. When the invention is in use, the heat release is low, no air holes and lines appear on the surface of the adhesive layer, and it can also play a role of flame retardancy, effectively improving the safety and reliability of the battery.

The problem to be solved by the present invention is to provide an active energy ray-curable ink that is compatible with plastic substrates represented by plastic substrates even when tetrahydrofurfuryl (meth)acrylate, tetrahydrofurfuryl alcohol, etc. are not contained or their contents are small. The adhesion performance of various substrates is also excellent. The present invention solves the above-mentioned problems by utilizing an active energy ray-curable ink characterized by containing a polymerizable compound (A) having a specific structure.
