Abstract: The present disclosure relates to a method for manufacturing the laminated film that is BSPC (Back Side Printable Clear) and has excellent interlayer adhesion. The method involves a first UV curing step and a second UV curing step and the laminated film includes a transparent film layer, a UV curable ink layer, and an adhesive layer. The first UV curing step includes disposing the UV curable ink layer on the transparent film layer and partially curing the UV curable ink layer by performing a first UV irradiation. The second UV curing step includes disposing the adhesive layer on a surface of the UV curable ink layer opposite the transparent film layer, and further curing the UV curable ink layer by performing a second UV irradiation.

Abstract: An inkjet printing method forming a decorative printed layer having a three-dimensional texture on a printing surface is described. The inkjet printing method includes: printing dots of curable ink that cure under a predetermined condition based on dot pattern data indicative of printed positions of the dots to be printed on the printing surface; and curing the printed dots. The dot pattern data indicates that: a distance between the adjacent dots becomes a distance where the adjacent dots before the curing are allowed to be maintained independently without bonding to one another in a first region; and the distance between the adjacent dots becomes a distance where the adjacent dots before the curing bond to one another in a second region different from the first region. Such a method may allow forming a decorative printed layer having a three-dimensional texture with a desired gloss level.

Abstract: A manufacturing method of a laminated sheet having a printed layer includes, given that a table that associates density data of a specific area included in image data with a burnup degree of the printed layer corresponding to the specific area at printing based on the image data is an image-burnup degree conversion table, identifying the image-burnup degree conversion table that satisfies a printing condition for the laminated sheet, acquiring printed image data that is image data for forming the printed layer of the laminated sheet, and calculating the burnup degree of the printed layer based on the image-burnup degree conversion table and the printed image data. Also disclosed is a laminated sheet having a printed layer, a system for manufacturing the laminated sheet, and a program for manufacturing the laminated sheet.

Abstract: A construction member of one embodiment of the present disclosure includes a decorative film and a pre-mask: that is laminated to the decorative film and removed alter application of the decorative film is described. The decorative film includes: a transparent resin film having, an embossed first surface and a second surface opposite the first surface; a printed layer disposed on the second surface of the transparent resin: film; and a colored adhesive layer disposed on or above the printed layer. The pre-mask includes: a support film having a first surface and a second, surface opposite: the first surface; and a pressure-sensitive adhesive layer that has an uneven surface and: is disposed on the first, surface of the support film. The first surface of the transparent resin film of the decorative film and the uneven surface of the pressure-sensitive adhesive layer of the pre-mask face each other.

Abstract: A radiation curable inkjet ink which has good surface curability even in air, and is capable of providing a cured product having low odor, good flexibility, and low-temperature impact resistance is described. In particular, radiation curable inkjet ink including from 20 to 40 parts by mass of a bifunctional urethane (meth)acrylate oligomer and from 50 to 80 parts by mass of a monofunctional monomer, based on 100 parts by mass of polymerizable components and an α-hydroxyketone oligomer and a benzophenone compound as photoinitiators are described.
