Title:
ADHESIVE SHEET, ARTICLE AND METHOD FOR MANUFACTURING ARTICLE
Document Type and Number:
Japanese Patent JP2021194823
Kind Code:
A
Abstract:
To provide an adhesive sheet which prevents thermal damage of insert parts by local heating in an insert part formation step of injection forming a coating resin layer on a back surface of the insert parts, suppresses generation of air bubbles in the molding obtained through the above step, and can maintain designability.SOLUTION: An adhesive sheet 5, which is used while being stuck to a surface on a side of a decorative layer of insert parts having a translucent resin layer and the decorative layer provided on a part or the whole of one layer of the translucent resin layer in this order, includes a resin layer A1 and a resin layer B2. In the resin layer A, a loss tangent in a temperature range of 200-220°C measured at a frequency of 3 Hz is within a predetermined range. The resin layer B is an adhesive layer (b) having a tensile storage elastic modulus at 200°C and a loss tangent in a temperature range of 60-200°C, which are measured at a frequency of 3 Hz, within predetermined ranges.SELECTED DRAWING: Figure 1
