昭５５−８９５６４号公報）も提案されている。In recent years, it has often been necessary for the surfaces of magnetic heads, etc. used in precision mechanical parts and precision electronic parts to be finished to a precision surface of, for example, micron or submicron order. An abrasive tape obtained by applying a resin solution containing fine inorganic powder dispersed in a resin solution and drying it to form an abrasive layer on a film-like base material for an abrasive tape. (For example, Japanese Patent Publication No. 53-44714)
However, an abrasive tape (Japanese Utility Model Publication No. 89564/1983) has been proposed in which the abrasive layer of the abrasive tape has a number of concave grooves for collecting abrasion particles.

ることが困難である等の欠点を有している。However, in the conventional abrasive tape having an abrasive layer in which a large number of concave grooves for collecting abrasion powder are formed, the abrasive layer is formed by a printing means, so the formation of the abrasive layer is troublesome. Ashi, Shikamo said Jitsukai 1977-
In an abrasive tape for polishing in which concave portions in a diagonal striped pattern are formed as shown in Japanese Patent No. 89564, abrasion powder is controlled according to the size and amount of abrasion powder generated during polishing. Because the configuration of the recesses for collecting the diagonal striped pattern is the width of the recesses and the spacing between the recesses, the polishing tape is capable of achieving a high-quality polishing finish without causing "white spots", for example. It has the disadvantage that it is difficult to

The size of the approximately regular hexagonal groove that corresponds to the tortoiseshell-shaped image line, the width and depth of the groove, and the width and depth of the spot-shaped groove are determined by the polishing tape. This may be changed as appropriate depending on the type of object to be polished and the polishing accuracy required for the object to be polished with this polishing tape, but in general, approximately hexagonal grooves are used. The distance between the hexagons, that is, the distance from the center point of the hexagon to the center of the adjacent hexagon, is about 10 to 300 μm. The width of the concave portion of the approximately hexagon is about 0.1 to 200 μm. Approximately 0

ある。The "Bénard cell phenomenon" that occurs in the coating layer obtained when the coating agent contains a large amount of inorganic components is caused by the drying of the coating layer formed by the coating agent.
In the process of solidifying and forming a coating layer, that is, in the process of solidifying the coating layer by evaporation of the solvent contained in the coating layer of the coating agent, the coating agent components in the coating layer form a coating layer. This is caused by convection in the direction perpendicular to the surface of the coating layer and surface tension applied thereto. A concave portion consisting of the spot-like concave portion remaining as a convection path when convection occurs is formed in the coating layer.

有するものであるからである。In addition, in the present invention, a polyester resin, a vinyl chloride/vinyl acetate copolymer resin such as a salt/vinyl acetate resin, or a mixed resin thereof is used as a binder component. This is because the coating agent has the property of easily causing convection of the coating agent components in the coating layer during the process in which the solvent contained in the coating layer is evaporated and the coating layer is solidified.

を有するためである。In addition, in the coating agent, the ratio of the binder component which is a solid component in the coating agent and the abrasive particles is 100 to 1 part by weight per 100 parts by weight of the binder component.
This is because if the abrasive particles are less than 100 parts by weight based on 100 parts by weight of the binder component, the polishing action in the resulting polishing layer may not be sufficient. , 1,400 parts by weight, there is a risk that the binder component will not have enough binding power, resulting in a polishing tape in which abrasive particles will fall off during the polishing process.

For those with a high viscosity of 0 c, p or more or a low viscosity of less than 7 c, p, the solvent contained in the coating layer by the coating agent evaporates and the coating layer solidifies. Because convection of coating agent components does not occur or the degree of convection is too small, the resulting polishing layer has no concave portions, or only concave portions that are too shallow to collect wear particles are formed. It is.

部が形成されなくなるためである。Further, the coating agent is applied to the surface of the polishing tape base material in an amount of 5 to 60 f (solid component)/W? This means that the application ratio of the solid component is 5%.
If the coating layer is less than 2/m2, the coating layer becomes a driving force for the convection of the coating agent components in the coating layer, which is generated in the process of evaporation of the solvent contained in the coating layer and solidification of the coating layer. The difference in surface tension and buoyancy between the lower and lower surfaces is not significant, and concave portions that can accumulate abrasion powder are difficult to form on the surface of the polishing layer, and the coating rate of the solid component is 60 t/rr. ? If the coating layer is dried by the coating agent, even after the surface of the coating layer has solidified, the solvent inside the coating layer will continue to evaporate due to forced drying, and foaming and cracking will occur in the polishing layer, resulting in a hexagonal-shaped image. This is because the formation of a concave portion consisting of a concave portion corresponding to the line portion and its center portion on the surface of the polishing layer is hindered, and a uniform concave portion is no longer formed.
