    • A drying oil such as isomerized linseed oil, dehydrated castor oil or the like oil which has an iodine value of more than 140 and a content of conjugated double bonds of less than 50% is reacted with isopropenylphenol and/or oligomers thereof in an amount, by weight, of 0.1-2 times as great as that of the drying oil in the presence of a small amount of an acid at a temperature of 65-150.degree. C. for 0.5-3 hours. By the reaction, isopropenylphenol and/or its oligomers are introduced to the drying oil while leaving the double bonds of the oil as they are without disappearance. The thus introduced oil is further reacted with a phenol or phenols under strongly acidic conditions to introduce the phenols thereto. The drying oil which has been introduced with the isopropenylphenol and/or its oligomers and also with the phenols is mixed with a phenol or phenols and then reacted with formaldehyde to give a modified phenolic resin. This phenolic resin is useful for making a phenolic laminate with improved flexibility, punching quality and water proof.

    • According to one embodiment, a light emitting element includes a light emitting layer, a cladding layer, a current spreading layer, a second layer, and an electrode. The light emitting layer is capable of emitting emission light. The current spreading layer includes a surface processed layer and a first layer. The surface processed layer has a surface including convex portions and bottom portions provided adjacent to the convex portions. The first layer is provided between the surface processed layer and the cladding layer. The second layer is provided between the surface processed layer and the cladding layer and includes a region having an impurity concentration higher than an impurity concentration of the current spreading layer. The electrode is provided in a region of the surface of the surface processed layer where the convex portions and the bottom portions are not provided.
    • 根据一个实施例,发光元件包括发光层,包覆层,电流扩散层,第二层和电极。 发光层能够发射发光。 电流扩散层包括表面处理层和第一层。 表面处理层具有包括与凸部相邻设置的凸部和底部的表面。 第一层设置在表面处理层和包覆层之间。 第二层设置在表面处理层和包覆层之间,并且包括杂质浓度高于电流扩散层的杂质浓度的区域。 电极设置在表面处理层的没有设置凸部和底部的表面的区域中。
