Paper manufactured from sizing agents with the poor brightness stability comprises a base layer and a pattern layer combined with the base layer. The pattern layer occupies a local area of the base layer. The base layer is formed by the first sizing agent. The pattern layer is formed by the second sizing agent. Difference exists between the brightness stability of the first sizing agent and the brightness stability of the second sizing agent, so that chromatic aberration is generated between the base layer and the pattern layer and a pattern of the pattern layer is shown on the base layer. The advantage that the sizing agents with the poor brightness stability are likely to be yellowed is utilized, the pattern layer formed by the sizing agent with the poor brightness stability is formed on the base layer formed by the sizing agent with the good brightness stability, and the pattern layer has the brightness different from that of the base layer, so that the shape of the pattern is shown to achieve the attractiveness effect. Accordingly, the sizing agent with the poor brightness stability such as high-yield pulp can be sufficiently utilized, the treatment technology for restraining yellowing does not need to be adopted specially, and meanwhile a consumer will not feel that the paper becomes old and has the consumptive willingness.
