SOLUTION: This intermediate film is a thermoplastic resin sheet having embossed patterns which are formed in its both surface respectively and each of which consists of a number of recessed and projecting parts, wherein each of the recessed parts of the embossed pattern in at least one surface of the sheet is formed into a groove- like or desirably linear-groove-like shape at a different level from those of the others so as to meet the relational expression Rzv/Rz>=0.25 (wherein: Rz is surface roughness of the embossed pattern formed in at least one surface of the sheet, and more specifically, the ten-point average roughness value measured as described in JIS B 0601 with a conical tracer having a 5 μm radius of curvature at the tip and a 90 deg. apical angle; and Rzv is surface roughness of a negative model to the embossed pattern formed in at least one surface of the sheet, and more specifically, the ten-point average roughness value measured as described in JIS B 0601 with a wedge-shaped tracer having a 1,000 μm width of the front edge and a 90 deg. angle between the opposite faces, as shown in the figure, while moving the tracer in the direction orthgonally intersecting the width direction of the front edge).

熱加圧して本圧着を行うことにより製造される。[0003] In this type of laminated glass, an interlayer film is sandwiched between glass plates and handled by passing through a pressing roll (handling roll method) or placed in a rubber bag and suctioned under reduced pressure (vacuum bag method). It is manufactured by pre-press bonding while degassing the air remaining between the substrate and the intermediate film, and then heating and pressurizing in an autoclave to perform main press bonding.

れる。The interlayer film for laminated glass has adhesiveness,
In addition to good basic performance such as weather resistance, penetration resistance, transparency, etc., interlayer films do not block during storage, and handling workability when sandwiching interlayer films between glass plates is good. Further, in order to eliminate air entrapment, it is required that the deaeration in the pre-compression bonding step be good.

照）。[0005] In order to satisfy such requirements, an emboss having fine irregularities is usually formed on the surface of the intermediate film. As a form of the fine unevenness, an embossment having a surface shape including a large number of convex portions and concave portions corresponding to the convex portions and forming all the concave portions so as to be continuous at the same level is disclosed (for example, Japanese Patent Publication No. 1-332776).

ものではなく、未だ改善の余地がある。However, in the above-mentioned conventional interlayer film, the blocking property during storage, the handling workability, and the degassing property in the pre-compression bonding step are considerably improved. When degassing under severe conditions, such as when manufacturing wide laminated glass or laminated glass with a large curvature, or when increasing the productivity of laminated glass, sufficient degassing and sealing properties are required. Not satisfactory, there is still room for improvement.

くなる。That is, when degassing is performed under the above-mentioned severe conditions, it is particularly difficult to make the sealing state between the glass plate and the interlayer uniform throughout, and the degassing and sealing properties are incomplete. When pressurizing and heating in an autoclave, pressurized air penetrates from a defective sealing portion, and bubbles are easily generated between the glass plate and the intermediate film.

The purpose is not only good blocking properties during storage and good workability when sandwiching an interlayer film between glass plates, but also excellent degassing and sealing properties in the pre-compression bonding step, An object of the present invention is to provide an interlayer film for laminated glass in which quality defects are improved.

In order to form such an embossment, an embossing roll method, a profile extrusion method, an extrusion lip embossing method using a melt fracture, and the like are employed in the same manner as in the related art. In particular, the embossing roll method is suitable for quantitatively obtaining embosses having certain fine irregularities.

In addition, those in which each recess is formed in a groove shape are preferably used. After forming a fine uneven pattern on the roll surface as described above, the surface is subjected to a blasting process using an abrasive such as aluminum oxide, silicon oxide, or glass beads to form a further fine uneven pattern.

In general, an uneven pattern formed of a number of ridges having a triangular or trapezoidal cross section and a number of grooves corresponding to these ridges is provided.
The ridges and grooves may be linear (linear, curved, or wavy) or lattice-shaped. In addition, an uneven pattern composed of a large number of convex portions formed of a quadrangular pyramid or a truncated quadrangular pyramid and a large number of concave portions corresponding to these convex portions is provided.

This is a ten-point average roughness measured based on JISB0601 by moving the stylus in a direction perpendicular to the tip width using a 90 ° facing angle. This is generally measured by a digital stylus electrical surface roughness meter.

The reason is that the distance between the convex and concave portions of the emboss (usually 2
With the use of such a stylus having a tip width of 1000 μm, a change in shape of a particularly deep concave portion among embossed concave portions is measured.

と密接な関係がある。The Rzv is a parameter indicating the level of the concave portion of the emboss, and it has been found that Rzv is closely related to the ease of air release during degassing and the sealing property. Note that Rz is a parameter indicating the state of the embossed protrusions, and is not only a resistance to the movement of air, but also has a close relationship with the crushability of the emboss during the joining process.

Excellent degassing and sealing properties in the pre-compression bonding process. During heating and pressurization in an autoclave, pressurized air penetrates from the defective sealing part and bubbles are generated between the glass plate and the interlayer. Experiments have shown that an intermediate film that is difficult to perform is obtained.

い作業が容易であることも判った。Although the blocking between the interlayers depends on the number of interlayers to be stacked during storage, an interlayer having a ten-point average roughness (Rz) of 20 to 100 μm is usually used.
In addition, these intermediate films may take into account the weight of 500 to 1000 sheets, and under such a load, if the intermediate film satisfies the above specific conditions, the blocking resistance is good and It was also found that the handling work during storage and during laminating was easy.

中間膜が得られる。In the intermediate film of the present invention, it is preferable that both surfaces have the above-mentioned specific surface roughness, but only one surface has the above-mentioned specific surface roughness, and the other surface has the conventional surface roughness.

For example, when an intermediate film made of a plasticized polyvinyl butyral resin sheet is used, specifically, pre-compression bonding and main compression bonding are performed as follows.
