水シートＳ’が作られる。The upper layer portion 10 of the waterproof sheet S 'is usually made of a synthetic resin sheet having excellent weather resistance and a hard layer.
Those having the pattern a are provided with the pattern a by ink printing on the back surface. On the other hand, the lower layer portion 11 is a soft layer in terms of walking property, workability, and the like, and a synthetic resin sheet to which many plasticizers different from the upper layer portion 10 are added in order to impart the softness is used. The two sheets 10 and 11 are heat-sealed to produce a waterproof sheet S ′.

を招く現象が生じている。[Problems to be Solved by the Invention] In the above waterproof sheet S ', after heat welding of both sheets 10 and 11, with age,
From one sheet 10 or 11 to the other sheet 11 or 1
A phenomenon occurs in which the weathering agent, plasticizer, and the like imparting the property to 0 are transferred, and the properties (weather-resistant or soft) of the sheets 10 and 11 are deteriorated.

好ましいことではない。[0005] In particular, the ink forming the pattern a and the plasticizer are compatible, and as a result, the plasticizer migrates from the lower layer portion 11 containing a large amount of the plasticizer to the ink pattern a side with time, and enters the pattern a. Then, the pattern a turns brown. This discoloration is promoted by light irradiation. Discoloration makes the appearance worse, lowers the commercial value, and even after the construction, the deterioration of the appearance is not preferable.
