Abstract
This process suppresses the deterioration of the decorative design of the decorative component due to degreasing. [Solution] The decorative laminate 40 is bonded to the adherend AB by a bonding layer 50. The decorative laminate 40 includes a surface protection layer 41, a design layer 42, and a barrier layer 43 in this order, from the first surface 40a to the second surface 40b. The surface protection layer 41 includes a cured resin. The barrier layer 43 is adjacent to the bonding layer 50. The elongation ratio of the decorative laminate 40 under at least one of the 25°C and 160°C conditions is 1.5 times or more. The barrier layer 43 has an infrared absorption spectrum of 1500 cm⁻¹. -1 More than 1600cm -1 The first peak P1 is located within the following wavenumber range, and 1600cm -1 More than 1700cm -1 The second peak P2 is located within the following wavenumber range, and 3250cm -1 More than 3350cm -1 It has a third peak P3 located in the following wavenumber range. In the infrared absorption spectrum of the barrier layer 43, the full width at half maximum of the third peak P3 is 250 cm. -1 That's all.
