A decorative base paper or a preimpregnated decorative base paper is finished with an ink absorbing layer for printing by the ink-jet method.

The invention relates to articles comprising a substrate comprising an ink receptive layer and an ink-jet printed image as well as methods of ink jet printing. The ink receptive layer comprises certain urethane-containing polymers and blends.

A chromene compound of this invention, as shown in the following formula:characterized by having an indeno(2,1-f)naphtho(1,2-b)pyran structure as a basic structure, and having a substituent which is a substituted or unsubstituted aryl group such as methoxyphenyl group, or a substituted or unsubsterituted heteroaryl group such as thienyl group bonding to a carbon atom at the seventh position of the indeno(2,1-f)naphtho(1,2-b)pyran structure. The photochromic compound exhibits a color tone of a neutral tint when it develops a color, features a high color-developing sensitivity and a high fading rate, and has a good photochromic resistance.

A photochromic cured product which has excellent photochromism such as high color density and high fading speed, excellent adhesion to a hard coat and high striping work efficiency. This cured product is obtained by polymerizing and curing a curable composition which comprises (A) a polyfunctional polymerizable monomer such as trimethylolpropane trimethacrylate, (B) a silyl monomer such as gamma-methacryloyloxypropyl trimethoxysilane, (C) another radically polymerizable monomer and (D) a photochromic compound. As for the contents of the polymerizable monomers, the content of the component (A) is 1 to 50 wt %, the content of the component (B) is 0.5 to 20 wt % and the balance consists of the component (C) based on the total of the components (A), (B) and (C). The photochromic compound (D) is contained in an amount of 0.0001 to 10 parts by weight based on 100 parts by weight of the total of the components (A), (B) and (C).

A decorative base paper or a preimpregnated decorative base paper is finished with an ink absorbing layer for printing by the ink-jet method.

An ink-jet recording material having a support and at least one ink-receiving layer, the ink-receiving layer comprising at least one binder and a cationized fumed silica prepared by copolymerizing at least one cationic monomer and at least one non-cationic monomer monomer in the presence of a fumed silica. A cationized fumed silica prepared by polymerizing the monomers in the presence of a fumed silica and a method of preparing an ink-jet recording material are also disclosed.

To provide a reversible thermosensitive recording medium comprising a support, a thermosensitive recording layer formed on the support, and a protective layer formed on the thermosensitive recording layer, wherein the thermosensitive recording layer contains an electron donative coloring compound and an electron acceptive compound, and the color tone reversibly changes depending on the temperature, and the protective layer contains a polymer of a composition containing two kinds of acrylate compounds selected from an acrylate compound having a pentaerythritol group and an acrylate compound having a dipentaerythritol group.

The invention provides a water-proof self-luminous printing film of the thickness of 0.150-0.156mm, and the film comprises an ink receiving layer, a connection layer, a light-storage photoluminescent film from top to bottom, wherein the ink receiving layer is prepared from inorganic stuffing, adhesive, color fixing agent, coupling agent, surfactant, cross-linking agent, fluorescent brightener and water according to certain proportion; the film has good water proofness, fast ink drying speed, clearer images after ink-jet printing and high color density and is self-luminous in the dark after absorbing external visible light; and when printed on the surface of the printing film, patterns or characters can be viewed in dark, and the film has a lighting function with low illumination. Wide application of light-storage self-luminous film products can be realized in home decoration, hotels, corridors, office buildings, cinemas, warehouses, cabins, underground passages, places needing to print a large area of high-precision patterns, and the like.
