There are no analogues that have both functions for general drafting and ppc, such as AD, and they have the disadvantage of being limited to each use.
（発明が解決しようとする問題点）
手書き及びＣＡＤを主とする一般製図用紙として、設計
者が特に要求する用紙の特性は、■筆記性、■抹消性、
■易読解性が主であり、かつ本体に■透明性、■平面性
、■寸法安定性、■強度（引張、引裂、耐折、剛度）等
の性質を有することが不可欠な条件である。(Problems to be Solved by the Invention) As a general drafting paper for handwriting and CAD, the paper properties that are particularly required by designers are: ■Writability; ■Erasability;
■Easy to read is the main requirement, and the essential conditions are that the main body has properties such as ■transparency, ■flatness, ■dimensional stability, and ■strength (tensile, tear, bending resistance, stiffness).
最近では特に手書き製図に使う筆記用具が多様化し、鉛
筆のみならず、０．１〜０．３ｍｍ程度の水性ペン、油

ましい。The average particle size is about 0.1 to 0.3μ, and the oil absorption (JIS
-510]) of 200m/100g or more is desirable.
又併用する珪酸塩の平均粒径が５μとがなり大きく塗着
層の平滑性が失われやすいのでこれを改善する役割を持
つ。In addition, since the average particle size of the silicate used in combination is 5 μm, the smoothness of the coated layer tends to be lost, so it has the role of improving this.

転移温度は５０℃〜６０°Ｃが最適である。The aqueous emulsion whose main component is acrylic copolymer resin (hereinafter referred to as acrylic resin) used as a binder must have good adhesion to polyethylene terephthalate film, and must have good solvent resistance and blocking resistance. It is desirable that the glass transition point is 50°C. Characteristics necessary for design and drafting paper include: 1) writability, 2) erasability, and 3) readability, but these largely depend on the hardness of the tracing film surface. In addition to handwriting, it is necessary to have a surface hardness that can withstand the force of writing, that is, the hardness of the writing instrument light (pencil lead, pen tip) and the force applied to the hand, so it is not possible for the surface of the coating layer to be too flexible. It is. The hardness of the surface often depends on the hardness of the binder contained in the coating layer (it also depends on the pigment), so
The acrylic resin used in the present invention has a glass transition temperature of at least 50° C. and is extremely hard. but,
If the glass transition temperature is 60° C. or higher, it is better to avoid using it because not only the adhesion to the substrate becomes poor, but also the coating layer may collapse due to cracking after coating. The optimum glass transition temperature is 50°C to 60°C.

を選択した。In addition, the water-soluble polyester resin used as a binder has the effect of increasing the interlayer adhesion between the coating layer and the polyethylene terephthalate film, as well as improving the friction and abrasion properties of the coating layer. As mentioned above, it is better to use a hard resin. In addition, it is necessary that it has particularly good compatibility with the acrylic resin and pigment used together. Here, a water-soluble polyester resin with a glass transition temperature of 40°C was selected.
アクリル系樹脂及び水溶性ポリエステル樹脂で成り立つ
バインダーの合計量は、顔料分に対して１３０〜１５０

では、設計製図用紙として必要な特性のうち、■筆記性
、■抹消性が著しく低下するがインキの乾燥性は」−昇
する。The total amount of binder consisting of acrylic resin and water-soluble polyester resin is 130 to 150% of the pigment content.
Weight percent is preferred. If the binder ratio is lower than this, among the properties necessary for design and drafting paper, (1) writability and (2) erasability are significantly reduced, but the drying properties of the ink are increased.
又、これ以上のバインダー比率では前述の挙動が逆転し
、■筆記性、■抹消性は上昇するがインキの乾燥性が低
下する。Moreover, if the binder ratio is higher than this, the above-mentioned behavior is reversed, and (1) the writability and (2) erasability improve, but the drying properties of the ink decrease.
更にバインダーであるアクリル系樹脂と水溶性ポリエス
テル樹脂の構成比率を変化させると様々な挙動を示す。Furthermore, when the composition ratio of the binder acrylic resin and water-soluble polyester resin is changed, various behaviors are exhibited.

着剤の基材の密着が落ち、いかに塗着面の表面硬度が高
くても塗着層が剥離脱落する可能性が強くなる。When the ratio of binder to pigment is 140% by weight, the mixing ratio of acrylic resin and water-soluble polyester resin is approximately 50:50 (45:55 to 55:4).
5) is good. If the acrylic resin is in excess, the adhesion of the coating agent to the base material will deteriorate, and there is a strong possibility that the coating layer will peel off, no matter how high the surface hardness of the coating surface.
又水溶性ポリエステル樹脂が過剰な場合は、塗着面の滑
り性が悪くなり筆記性が劣る他、塗着面の硬度が低くな
り鉛筆による筆記後の抹消性が著しく悪化する。If the water-soluble polyester resin is in excess, the slipperiness of the coated surface becomes poor, resulting in poor writability, and the hardness of the coated surface decreases, resulting in a marked deterioration in erasability after writing with a pencil.

ためＦレーシングフィルムとしては使用しにくくなる。The mixing ratio of silicate and precipitated calcium carbonate in the pigment may be 7:3 or 5:5. If the amount of silicate is more than this, the smoothness of the coated surface will be significantly deteriorated, and the writing performance and printing performance during plain paper copying will be poor. If the amount of precipitated calcium carbonate is more than this, erasability deteriorates and the applied layer becomes extremely opaque. In other words, it loses transparency, making it difficult to use as an F racing film.

性が低下する。The thickness of the layer formed using these coating agents is suitably 6 to 10 microns. If the layer is less than 6 μm, the layer is thin, so that not only the absorbency of all inks deteriorates, but also the writing and erasing properties deteriorate. Moreover, if it exceeds 10 tt, the slipperiness deteriorates, and not only the writability deteriorates greatly, but also the transparency is lost. Furthermore, when plain paper is used as paper for copying, it is necessary to apply a special resin to the back side of the polyethylene terephthalate film to prevent static electricity from being applied to the back side of the polyethylene terephthalate film to prevent double feeding. The antistatic agent used here is a 50:5 ratio of acrylic resin and water-soluble polyester resin used on the surface.
An antistatic agent containing a special polymer activator is added to the mixture at 0% by weight. The thickness of the coating layer is preferably about 0.3μ; if it is less than this, it will be difficult to uniformly wet the polyethylene terephthalate film, and
Sufficient antistatic properties cannot be provided, and if the coating exceeds this level, the slipperiness between the contact surfaces (in this case, the front and back antistatic surfaces of the polyethylene terephthalate film) during plain paper copying will decrease.
