    • The present invention provides a recording medium comprising a substrate having a glossy coating thereon, wherein the glossy coating comprises a binder and first and second groups of particles, wherein: (a) the first group comprises metal oxide particles, wherein the metal oxide particles are aggregates of smaller, primary particles, (b) the mean diameter of the primary particles is less than about 100 nm, (c) the mean diameter of the aggregates is from about 100 nm to about 500 nm, (d) the mean diameter of the particles in the second group is less than about 50% of the mean diameter of the aggregates in the first group, and (e) the ratio of particles in the first group to particles in the second group is from about 0.1:1 to about 10:1 by weight. The glossy coating of the inventive recording medium has an excellent rate of liquid absorption, a relatively high liquid absorption capacity, excellent adhesiveness, and a non-brittle, crack-resistant, glossy surface. Also provided is a method of preparing a recording medium and a coating composition useful in the preparation of a recording medium.
    • 本发明提供了一种记录介质,其中包括在其上具有光泽涂层的基材,其中光泽涂层包括粘合剂和第一和第二组颗粒,其中:(a)第一组包括金属氧化物颗粒,其中金属氧化物颗粒为 (b)初级颗粒的平均直径小于约100nm,(c)聚集体的平均直径为约100nm至约500nm,(d)平均直径为 第二组中的颗粒小于第一组中聚集体的平均直径的约50%,和(e)第一组中的颗粒与第二组中的颗粒的比例为约0.1:1至约 10:1重量份。本发明记录介质的光泽涂层具有优异的液体吸收速率,较高的液体吸收能力,优异的粘附性和非脆性,抗裂纹的光泽表面。 还提供了制备用于制备记录介质的记录介质和涂料组合物的方法。
