摘要： PROBLEM TO BE SOLVED: To realize the easy decoration of a three-dimensional uneven surface formed of both lengthwise and crosswise recesses and projections and facilitate continuous production, and further, eliminate damage to be generated in roll parts by the uneven part of a base with an uneven surface by bringing a laminated sheet for decoration into contact with the base with an uneven surface under pressure through following up its uneven surface contour, using an impact pressure and adhering and setting the laminated sheet to the base. SOLUTION: Bases with tan uneven surface 1 to which a laminated sheet for decoration 3 is stuck are conveyed one by one using a base conveying device 2, and the evaporating component of a first coat is volatilized and dried by a drying device 41 after the bases with an uneven surface 1 are given a first coat by a coating device 40. The laminated sheet for decoration 3 is exposed to a solid particulate 5 which collides with the sheet 3 after being ejected from a blow-off nozzle 15 with an air current. In this case, a variation in the momentum of the solid particulate 5 at the time of impact represents an impact pressure. The laminated sheet for decoration 3 is brought into contact under pressure with the bases with an uneven surface 1 by the impact pressure of the solid particulate 5 and is stretched even into the recessed part of the uneven surface of the base with an uneven surface 1, so that the laminated sheet 3 is deformed. Thus the laminated sheet 3 adheres to the uneven surface contour of the base 1 with a heat fusion-type adhesive which displays adhesion by following up said uneven surface contour and thus the laminated sheet 3 is laminated to the base 1.

摘要： PROBLEM TO BE SOLVED: To efficiently produce a decorative material having a three-dimentional irregular surface and a durable decorating layer. SOLUTION: Solid particles 5 are made to collide with an irregular surface of a substrate 1 onto which heat transfer is made from a rear surface side of a transfer sheet 3 opposing a transfer layer being a decoration layer to bring the transfer sheet into a pressured contact with the irregular surface of the substrate by using the colliding pressure to effect a transfer. An ionizing radiation cure type adhesive is used for an adhesive to bond a transfer layer to the substrate. When the transfer sheet and the like applied with the ionizing radiation cure type adhesive enters a chamber applying the colliding pressure of the solid particles, the ionizing radiation cure type adhesive is supplied in a solventless state to cure after the colliding pressure is applied.
