## Abstract

To provide a resin formed product with a label, for which information can be provided on the label without using ink and the information can be visually recognized from the external appearance even in a condition where the label is adhered. A resin formed product 20 to which a label 10 is adhered, the label 10 being formed by laminating a layer containing a porous base layer A and an adhesive layer B adhered to a surface of the resin formed product. On the label 10, a rough part 11 having a relatively rough surface roughness and a smooth part 12 having a predetermined pattern having a relatively smooth surface roughness are formed, and a cross-sectional porosity of the label of the smooth part 12 is from 0 to 93% relative to the cross-sectional porosity of the label of the rough part 11.

## Claims

### Claim 1

A resin formed product,
the resin formed product being a resin formed product (20) to which a label (10) is adhered,
the label being formed by laminating a layer containing a porous base layer (A) and an adhesive layer (B) adhered to a surface of the resin formed product,
the label has a rough part (11) having a relatively rough surface roughness and a smooth part (12) having a predetermined pattern (12a) having a relatively smooth surface roughness, and
a cross-sectional porosity of the label of the smooth part being from 0 to 93% relative to the cross-sectional porosity of the label of the rough part.

### Claim 2 (depends on 1)

The resin formed product according to claim 1, wherein
when the surface roughness of the rough part (11) is Rzr and the surface roughness of the smooth part (12) is Rza, the Rzr is 25 μm or greater, and Rza/Rzr is less than 0.6.

### Claim 3 (depends on 1)

The resin formed product according to claim 1, wherein the smooth part (12) is formed by heating and pressuring the label (10) from a front surface side or a back surface side.

### Claim 4 (depends on 1)

The resin formed product according to claim 1, wherein
the adhesive layer (B) has a porous adhesive layer (B1), and
when the label is released from the resin formed product by splitting the porous adhesive layer, patterns (12b, 12c) corresponding to the smooth part appear on a released face of the released part (10a) of the label that has been released from the resin formed product and a released face of the remained part (10b) of the label that remains on the resin formed product.

### Claim 5 (depends on 1)

The resin formed product according to claim 1, wherein the adhesive layer (B) has a heat seal layer (B2).
